Sanders isn't stong...he backed down from black lives matter. He wants to take guns and raise taxes...he's a communist.
Do you think the dems will intro some new candidate at the convention, if hilary is shit and bernie is a joke? They CANT lose to Trump, and that may be the case. You intro a Gore, a Biden, a Bloomberg, whoever, with 11 weeks until the election... may not be enough time for Trump to destroy the person.
imagine if the DNC announced Warren/some retired general as the ticket. holy crap, that'd be huge.
