Clinton needs to win at least 1 of IL, MO or OH for appearances sake. Otherwise she starts to look like a regional candidate, especially with the rest of March in Bernie's favor.
She doesn't actually need to. If she loses those 3 narrowly but wins NC/FL in blowouts, she'll net enough delegates to be unstoppable, "regional candidate" or not.
The regional candidate who leads actual primary voting 60/38 and has approximately 1.8 million more votes. This is what I've concluded: Sanders supporters will play mental gymnastics to find any way to minimize Hillary's wins and maximize Bernie's. A one point win in Michigan - the race is turned on its head. A 30 point blow out for Hillary in Florida - well, she only appeals to minorities and old folks. But, at the end of the day, the only thing that matters is delegates and she will earn more than Bernie on Tuesday, likely by more than 100. Then he can win the caucus states coming up but she locks and loads again for NY on the 19th and then PA and MD on the 26th.
