I couldn't agree with PH more. What TOM either doesn't understand, or refuses to admit, just any Dem won't do. The Independent electorate appears, from all polls, to dislike the "progressive" agenda of Warren and Sanders. Dems need to pick a candidate who can beat Trump in swing states. Both coasts will follow whomever the Dems select, but PA, FL, OH, etc are a different matter.
In 2016, I often said that the only reason Trump could win, is he's running against Hillary. But I truly believe the reverse of that was true as well. Don't get me wrong; I'm voting (again) against Trump. But the Dems have to field someone who is at least palatable to swing voters. And they've shown an amazing talent so far trying not to.
