Lester . Andrea mitchell, thanks so much to talk about. Lets bring in our political director, the moderatat of meet the press, chuck todd. Chuck, if trump does well tomorrow, what are the points in which they can other republicans can stop him . The only way they can stop him within the party is to deny him the delegates he needs to get the nomination. To do that, he does well tomorrow night, then it becomes imperative that they defeat trump in march 15 in ohioo meaning evy other candidate other than john kasich decides to campaign there. Maybe rubio says ill let kasich go there and rubio has to win his home state of florida and maybe they find somebody else to rally a aund and beat him in illinois and north carolina. Thats the only way they can do it within the party, but if they dont succeed by march 15th, theres nothing they can do, cant deny the nomination so thirdparty route. Ive heard rumors of finding a candidate, itt romneys name. Theres a Constitution Party out there that has ballot access. If they want to start a third party, youd have to do it within the next couple of weeks to actually get ballot access, but this stuff i i real, and it gets very real on march 16th if donald trump continues to roll. Havent ever seen anything like it. Not since 1860 and the wigs. The Republican Party was born out of another conrvative party the whigs breaking apart. Maybe history is truly repeating it self.

Clinton Campaign Officials say they feel confident heeding into super tuesday after that big win in South Carolina, fueled largel by clinton hoping to build on that tomorrow. Senator sanders vowing not to give up, but he does have a steep climb, particularly if you look at the numbers, lester. The official nbc news delegate count shows clinton with 519 delegates and sanders with 86. If you only take into account super delegates, typically Party Leaders who get to choose who they will support, clinton gets 428 to sanders 21, a 20field advantage. Clinton is up with ads in all of the super tuesday states and sanders with ads in five of them, smaller, less diverse states like colorado and massachusetts. Still, sanders has a lot of cash on hand which means no matter what happens tomorrow that could allow him to stay in this race indefinitely. Lester . Kristen welker tonight, thank you.
