Trump would lose by 15 points to Sanders.
Nobody in their right mind who wants Trump, also wants him running against Sanders. That's my opinion.
There will be a moment on the DNC floor like there was 4 years ago when they purposely left out God and Jerusalem out of their platform.
Sanders may may swallow a big pill and leave his followers with no leader, but that doesn't mean his followers will turn out in November.
The RNC convention went really well, this leak, IMO, was released now to try and throw a wrench in DNC convention, starting with the meetings. Bernie has a massive decision on his hands now. Either show his followers that he stands with them, or show them that he'll stand against the very corruption he railed against all this time.
My guess is he's going to go with a "yeah, but Trump" argument. Not sure that's enough.
