lowering coming from the trump campaign. i should note, of course, other candidates are also facing the same challenges as iowans are being warned to stay off the roads because of these blizzard like conditions that you can see here that are spreading across the state. this is what a highway looked like just today. drivers clearly can barely see out their windshield. the question is, of course, getting people motivated to come out and caucus when it is going to be a high of minus 4 on monday. now iowans are tough. they know how to deal with a winter storm and they take their caucuses very seriously. but to pass the caucuses, they have mostly been held in balmy weather now. with windchills it could feel minus 40 in some parts of iowa on monday. i should note despite these dangers, candidates are still asking the voters to bundle up and come out for them that night. >> i'm concerned because i want people to be safe on caucus
