Newsroom at kcrg dot com. The president ial candidates have just four days left to win support from voters before the Iowa Caucuses monday night. But how often have the caucuses actually chosen the eventual president ial candidates . Since 1976, only three republican candidates who won the Iowa Caucuses have gone on to become the nominee. Thats not counting incumbents. And in that same time frame, democrats fared a little better, with five candidates becoming the nominee. The last time around democrats selected incumbent barack obama in an uncontested race. And Republican Voters chose Rick Santorum as their caucus winner. Santorum went on to win 10 more ates. But mitt romney was the eventual nominee. Kcrgtv9s Iowa City Bureau chief mark carlson joins us now. Mark, experts say the Iowa Caucuses arent always about winning . Yes. Experts say its not about winning, but its about where you finish. 15 back in 200808ike huckabee won the gop iowa cauaus. Now, 8 years later crowds at his events have shrunk, to at times only a couple dozen people. Its old fashion, grassroots, hand to hand combat, and i think thats what ultimately wins causes in iowa. Each race is different, and somebody who had a chance 8 years ago oo4 years ago, if they werenttuccessful, well now its a different race, its a different dynamic. While huckabees story may lead people to think that iowans arent very good at picking president s. But iowans get even better when it comes to narrowing the field, and thats what ui Political Science professor tim hagle says the caucuses are all about. The purpose isnt to pick the nominee or the winner if it were we would get even more grief from the other states who would say oh well gee after iowa its over, well its not over, our job here in the iowa and thats exactly what hagle says iowans do best. The last six president s all finished in the top three in iowa. Our job is to separate the contenders from the pretenders, people that really arent or arent serious or at least not competinin putting uncommitted voters aside only one time has the gop or democratic nominee not finished in the top three in their parties iowa caucus. So the saying, theres three tickets out of iowa is very accurate. We take this very seriously, we are very educated about the candidates their positions and so were kind of serving as a committee and say to the rest of the country, okayl here is ww we recommend. Johnson county democrats chair aartha hedberg says wans should be proud of their record. Nonotheres only one thihi left to do. Make more history, and it all starts right here in iowa. I want to see everybody turn out to their causes all across the state isnt an extremely important process. Hagle says that old saying, iowa may be challenged th year. Thats because thehe are only three democratic candndates, while the gop has a huge field. Well have to wait and see. In iowa city, mark carlson, kcrg tv nine news.

The mother and brother of former hawkeye Football Player tyler sash say his diagnosis of a degenerative brain disease prprvides them with morere answers about his behavior right before he died last september. They appeared on espns program, outside the lines, today. The Concussion Legacy Foundation confirmed sashs diagnosis of cte on tuesday. The 27 year old was a defensive back for theawkeyes und later for the nfl new rk giants. He suffered at leasastwo concussions before the giants cut him in 2012. Sash died last september from a fatal mxture of pain killers. After his death, his mother donated his brain to be tested for c te. She said today the diagnosis gives her a little bit of closure. It was clarity, yoknow it helpep us understand what was going g. Things seemed totoake sense when we realized the parts of the brain i think he was kind of caught in a situation where he didnt know what to do, he was not feeling right and he knew he didnt feel right, didnt feel like he could perform the same way that he could before but he felt like if i dont, theyll call somebody else and i dont have a job. Before sashs death, he had been suffering from bouts of confusion, memory loss, and minor fits of temper. Those are common symptoms of cte. Less than a year after coming under criticism for their euthanasia rates, the Dubuque Humane Society says is saved a record mber of animals. In 2014, the shelter euthanized more than 12 hundred cats and dogs. Then, last spring, the Humane Society starting using a different methodology to decide what makes an animal adoptable. In 2015, staff put down just two hundred 88 animals. Thats about a 75percent direreors say theyre dodog more to teach people who adopt how to rehabilitate those cats and dogs. They become stressed out in a new environment. To adjust to being here we are also giving them more time with our staff to get used to people so they have those interactions. That decreases ananety which reduces aggressive. Directors also dropped the kitten adoption fee from 110 dollars to 50. Older cats used to 75 dollars to adopt. Now they are 25. After a weather delay earlier this week, workers tore down an old water tower today in north liberty. Boom the city built the tower in 1976, and began municipal Water Service the next year. But the tower had been unused for years and was deteriorating. So the city hired a company to take it apart piecebypiece. North libertys water superintenden t says the city had to wrap up contracts with cell and 15 05 this tower has been removed, actually, unhooked from the Distribution System since probably 2010, so it hasnt served any purpose and would have been down a lot sooner except for trying to work out those contracts with the companies. Its a 200thousand gallon water tower. Many who remember when it was built spent time watching it come down and taking pictures. Since it was located right next to the fire department, fire crews say theyd like to exexnd the department onto the land by adding a couple of truck bays. If were going to do that as a state or a country, its going to take a lot of education about the need to do it the ntsb wants states to lower the legal blood alcohol limit for drunk driving. But is there any interest . Stay with tv9. The legal limit for drinking and lower. That is, if states adopt a change proposed by one federal agency. The National Transportatio n safety board would like to lower the legal blood alcohol limit for drunk driving to point zero5 per cent. Right now the limit is point zero8. The board is trying to reduce the number of alcoholrelated traffic deaths. Te ntsb says a 170 pound man with an empty stomach drinking three averages beers or glasses of wine in an hour would have a blood it takes four to five glasses to get to the current limit. As for a 130 pound woman, it takes just two drinks an hour on an empty stomach to reach zero point five per cent. And three to four drinks puts them at point zero eight. Kcrg tv nines Dave Franzman reports that so far not a single state legislature has proposed making the change. Back in 2003, iowa lawmakers, and many in other states, did drop the drinking limit for driving under the influence. But one lawmaker remembers it wasnt exactly the argument for safer roads that did it. The reason why it passed is because of the threat of loss of highway funds and even with that, there were a number of people who voted against the change passing the lower limit 45million dollars in federal incentive road funds during the next three years. Senator hogg believes it might take something similar from the federal government to get lawmakers interested now. But some would support the zero. Point. Fi ve drinking limit common in foreign countries. Verna kuehl lost a daughter in an accident in which alcohol was involved and would support a point zero five limit. I would think that would make people consider drinking less and being more aware of the situations before they get behind the wheel of a vehicle i think it would be good to have something to make you think before you drink further. The ntsb cites statistics showing 13 percent of drivers admit theyve drivn when they thought they were close to the legal drinking limit now. But senator hogg says hes heard absolutely no talk in the statehouse about drinking limits again. Dave franzman kcrg tv9 news. Source, kcrgtv9.

However, the hawkeyes are facing one of their toughest matches of the year at 8th ranked maryland. First time iowa has ever been to the xfinity center. Mike gesell puts the hawkeyes on the board first as he gets the easy drive to the basket for the dedece. Iowa trails. The iowa Womens Basketball team will take the court in 30 minutes at michigan. Since starting 20 in the big ten, the hawkeyes have really struggled losing three consecutive games, and five of their last six. One of those losses was to michigan, they had a 17point lead in that game. Get that win and gegeus covers up a up a lot of aches and pains. As soon as we get that win, i really think were going to be heading the right up the white flag. No way, no way. I think forward to a rematch.

Jordan bohannon is entering his senior year for the linnmar Boys Basketball team. Its not just his final year, but hes also the last of the four bohannon brothers to go through the program.

I try to at least make 500 shots during the summer and at least put up 500 during the season. I think the main thing is just try to get my shot off as quickly as possible because obviously im not the biggest kid. Im going to have get my shot off quick in the big ten. I think his range is the thing thats really developed. Hes had a couple of games where he shot 30 its effortless. For the past decade, weve heard the name bohannon in the linnmar program. Jordan has three older brothers jason, zach and matt. All three led the lions to a state title, something jordan hopes to do this year. I look up to my brotherer immensely. Everything theyve e done for r is program its been in a positive way. Theyve been such positive role models for this community. Jordan will take his talents to the university of iowa next year. His brothers have also helped him learn about the next level. I try to take my smarts from zach. Hes really intelligent on the court. He always helps me out each better. Jason, obviously is a great shooter. Him coming from wisconsin and helping me prepare for the big ten is just huge. And then matt, hes just one of the hardest workers ive ever seen. He wasnt getting the interest he should have at the beginning, but the recruiting process works. Guys are still looking. What an opportunity for coach mccaffery taking on jordan.
