Senator sanders was looking for new momentum on saturday. And he got it with wins in those two key caucus states.

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 both candidates will spend much of the day getting ready for tonights 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 morning to you. 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 participate. And the one primary that cruz 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 connect the dots back 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 rubeio 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 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 some life on tuesday in michigan 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 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 margins he loses to her in 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. Hour blew across Northern California from saturday into sunday, dumping heavy rains that should continue off and on throughout to the today. Trees down, Power Outages across the city of sacramento. The storm drenching neighborhoods, submerging cars and homes. Almost knee deep and it is really bad. Reporter californias highway 70 overflowing.

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 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 potentithe 30s to near 40 degrees. Expect sunday to be sunny and with full sunshine temperatures will warm to near 60 degrees this afternoon. Today will be the coolest day this week.
