Only primaries coming up that Bernie Sanders really has a shot in are Nevada and Massachusetts.
just saw a poll showing him ahead in colorado. he'll do well in western states as well. after he gets through the bible belt he still has a good shot in states like WI, michigan, oregon, washington. Take a look at nate silvers analysis:

as you can see, even with clinton having a 12 pt national lead, bernie is still doing ok in states like min, colorado, kansas, maine, idaho, utah, alaska, wa, hawaii, wi, montana.
The really interesting thing is when they are tied nationally he picks up much bigger leads in states where clinton is only marginally holding on right now.
Also, has hilary ever been regaining the support she's losing? Cause so far the flow of people switching from one candidate to another has been all in bernies direction. It stands to reason that if bernie can hold on and maintain momentum, he's continue to cut into clintons lead.
So where does that leave us?
A nevada win or close loss is going to bring in more money for him, and get even more people that haven't been paying attention to him taking a second look. The more people hear and find out about bernie the more they like him.
South carolina is going to hammer him.. obv. So it depends on how much he can mitigate the damage.
Then he has to weather super tuesday which has a lot of bible belt states.
But if he can hang on through that and just maintain... if he can make it so clinton doesn't blow him out of the water in SC, and if he pulls closer to hillary nationally then he actually has a decent fighting chance.
