But on Sunday on NBC's "Meet the Press," Sanders acknowledged that coming close — as he also did in Iowa at the beginning of the month — isn't enough. With Super Tuesday on the horizon, he agreed with host Chuck Todd that moral victories will no longer suffice. Here's part of their exchange:

Todd: Don't you have to beat her in a place like Texas or Virginia or Tennessee? A big state, to say, "You know what, I can win this nomination. I can't just come close." Don't you have to do that?

Sanders: No, you're right. Look, look, at the end of the day, what you're saying is true. You need delegates. And as you know, these are state by state, proportional delegates go out. We're looking hard at Michigan. We think we have a pretty good shot at parts of Texas. So trust me, we are focusing very hard on trying to get as many delegates as we can.

Sanders also said that he thinks he has a "good shot" in Colorado, Minnesota, Massachusetts, Oklahoma and, naturally, his home state of Vermont.

Eleven states will hold primaries and caucuses to pick the Democratic nominee on March 1, making Super Tuesday one of the most critical days on the electoral calendar. The RealClearPolitics polling averages show that Clinton is leading everywhere but Vermont, but some of the polling data are outdated, making the current state of affairs a bit murky.
