Count. Total number needed to secure the democratic nomination. We have complete coverage of both races beginning with nbcs Gabe Gutierrez. Gabe, good morning. Reporter good morning. Donald trump seemed almost unstoppable after super tuesday, now, ted cruz is picking up marco rubio to drop out. Hoping to emerge as the antitrump this morning ted cruz is soaring after Super Saturday. Were seeing republicans coalesce around our campaign because ours is the only campaign that has repeatedly beaten donald trump. The texas senator pulling off decisive victories in kansas and maine. But donald trump still the frontrunner, trouncing his rivals in louisiana and kentucky. I want to congratulate ted on maheine and on kansas and he reporter the billionaire trying to fend off the gop establishment. Donald trump is a phony, a fraud. Reporter in the first contest since mitt romneys blistering attack. Trump skipped saturdays conservative Political Action conference or cpac and came in a distant third in its straw poll. As a party, we should come together and stop this foolishness. Marco rubio reporter marco rubio, a distant third in kansas and today hes hoping to scrape up delegates in puerto ricos primary after campaigning there overnight. Roughest period in the Campaign Given the makeup of the electoral map. Reporter and now hes feeling the heat in florida, his mustwin home state. But cruz is upping his ground game here, trying to squeeze out rubio and make it a twoman race. Trump now calling on the florida senator to drop out. I would love to take on ted one on one. That would be so much fun he cant win new jersey, he cant win pennsylvania, he cant win california. I won ted one on one, okay. Reporter here in florida, more than half a million republicans have already voted, either early or absentee. And, craig, as if this entire race wasnt already out of a movie, today john kasich is campaigning in his home state of ohio with arnold schwarzenegger. California governor is with Gabe Gutierrez in jacksonville, thank you. Over to the democratic side, Bernie Sanders picked up some big wins in kansas and nebraska. Hillary clinton countered with a landslide victory in louisiana which widened her delegate lead. Nbcs Kristen Welker is in flint, michigan where the candidates debate later tonight. Good morning. Reporter good morning to you. Senator sanders was looking for new momentum on saturday. And he got it with wins in those two key caucus states. But as you point out, secretary clinton did net more delegates than she was already far ahead in the delegate count, making beat. Senator Bernie Sanders. Reporter riding high off victories in nebraska and kansas, senator Bernie Sanders at a democratic dinner detroit saturday. We will win in november. If we have a large voter turnout. Reporter secretary clinton at that same dinner also had reason to celebrate, earning a victory in delegate rich louisiana. I am thrilled were adding to our pledge delegate count. Reporter punctuating her delegate lead, each candidate focused on whats ahead. Im grateful to everyone who turned out to support us. But now all eyes turn to michigan. Reporter and with michigan voting tuesday, clinton isnt taking anything for granted. Her top surrogates former president bill clinton and daughter chelsea will campaign here, sanders aides say a win in michigan would prove he can be competitive in larger more diverse states. Sanders signaling a new focus on independence. The way to the white house is independents and to make sure trump does not win independents. Reporter both candidates preparing to face off tonight at a debate in flint, where sanders will likely take aim at clinton over her support of trade deals like nafta, unpopular in the west belt. Clinton will continue to paint herself as the candidate with the realistic policies and there will be no shortage of jabs for the republican contenders. Really, you just want to pull your hair out when you see that insult fest that goes on. On our worst day we will be infinitely better than the republicans on their best day. Reporter both candidates will spend much of the day getting ready for tonights debate and the flint water crisis will be a central topic with residents demanding specifics from both of the candidates and this has been an issue that has resonated all across the country, particularly with africanamericans. Erica . Kristen welker for us this morning, thank you. Chuck todd is nbcs political director and moderator of meet the press. Good to see you, my friend. Good morning, craig. Good to see you. These were the first contests since romneys passionate plea for trump for folks to dump trump. We saw the piling on thursday night at the debate. How real is the possibility that these antitrump forces are starting to pick up steam and that this is, in fact, a twoman race . Well, i have to say i want a little more information. There is two ways to look at what happened yesterday. On one hand, yes, maybe this is a coalescing, maybe ted cruz has some momentum, splitting the four states and actually netting more delegates than donald trump. However, it is also four states that were closed republican contests meaning independents and democrats couldnt participate. And the one primary that cruz did caught up and did very well against trump, louisiana, was another state that touches the state of texas. So what happens tuesday . Michigan, mississippi, those are places that trumps heavily favored. If we see him struggle there, then i think it is time to thursday from romney to that debate to a coalescing. But i can tell you this, i think one clear piece of evidence from yesterday is that if there is an antitrump candidate, it is cruz. Marco rubio with three thirds and a fourth, i dont think it will be him. Rubio focused on florida. But ted cruz is really focusing there too, opening a number of new offices in state, trying to steal that momentum. What happens to marco rubio moving forward . Is there something he can do between now and march 15th . You know, i dont think so anymore. I think florida is everything for him. He needed to win somewhere else, though, in this sort of in between week between the two super tuesdays and now it doesnt look like he has that opportunity at all. What hes got to fear, on tuesday, in mississippi, and michigan, john kasich has put extra focus actually on both states. What if rubio finishes fourth in both states, one week before he tries to win the florida primary . It could really zap momentum for him. I think there is a lot of pressure on marco rubio to show or mississippi if he has any hope of catching trump in florida. Lets turn to the democrats quickly. Bernie sanders picking up two states yesterday, but, again, these states, like the others he picked up, largely homogenous. I want to show our viewers the delegate count now for democrats so they can see where this thing really stands. Hillary clinton with literally almost twice as many delegates as Bernie Sanders right now. Is there still even a path for sanders to victory at this point, chuck . Well, it would mean Hillary Clinton would have to collapse, he would have to win more than 60 . Were now at the point he has to win more than 60 of all remaining delegates in order to somehow capture this nomination. Yesterday was a prime example of why it is going to be so he won two states. She won one. Guess who won more delegates for the night . She did, because she won africanamericans by such a large margin in louisiana. She won the whole state by a large margin. And when she loses to sanders, she doesnt lose by the same states where she wins. This path is becoming less and less viable by the day for him. Chuck todd, thank you very much, good to see you. Well be watching when your guests this morning on meet the press, former republican president ial nominee mitt romney. Want to turn to that wild weather that we mentioned hitting Northern California. It is the start of what is going to be a big storm system, which will roll across the country this week. Well have dylans forecast in a moment. First, sheinelle has more details on the system. Yes, after a relatively dry february, march is turning out to be a very wet one on the west coast with the series of storms moving in from the pacific. It caused massive flooding in Northern California overnight, claiming at least one life.

But, dylan, talk to us about the Stormy Weather out west and what we can expect across the country. Well, we are going to see wet Stormy Weather out west. But each one will get easier, id say. We had the bulk of the heaviest rain yesterday where we did get reports of eight inches of rain. We saw wind gusts in the highest peaks in mount diablo of 88 miles an hour. A wild storm system that moved in yesterday. Well see more wet weather tonight and tomorrow morning and another storm on tuesday. We are looking at additional two to four inches of rain and also another two to four feet of snow in the sierra mountains. Want to point out as the whole system moves eastward, we are looking for the possibility not of a Severe Weather outbreak, but isolated tornadoes possible through the plains, down into texas. We could see large hail and flash flooding. And we also need to focus on the rivers through the midwest as this transitions over to some heavier rain. We could end up with about three or more inches of rain with isolated higher amounts and that could lead to river flooding. More of the springtime setup where you get the severe storms and the potential for significant flooding. Across the country. Now heres a peek out your window. Good morning everyone. Lots of sunshine later on today. Little milder than yesterday. A High Temperature of 46 degrees. Less breezy as well. Were starting to get that warmup going today. A nice sunday ahead.
