“Sanders crushes Trump”
I don’t think that will happen.
I agree. A lot of Bernie supporters will switch to Trump in the general because they want real fixes, not communist mumbo-jumbo.
I think you are right. During a primary candidates who are not seen as having a chance to win their own parties get a kind of generic "other member of the party without baggage" presumption in general election matchup polls. Kasich had it till the end. Cruz had it, and then lost it when it seemed he had a shot at beating Trump. If Bernie pulled off an upset win of his party's primary he would lose that "generic other Democrat" mantle and the crazy socialist would get crushed.
“Sanders crushes Trump”
I well remember when PIAPS was “crushing” Trump. Now it’s an old communist who’s crushing him. Seems like almost ANYBODY can crush Trump.
