@Geoffberner I see hyperbole is your thing. Biden is not literally unable to “finish whole sentences on national television.” If you looked at the transcript you would see that, sentence by sentence, Biden spoke far more grammatically and coherently than the other guy. Surely you know that, so really, don’t exaggerate.
My opinion is that a convention, full of discord and confusion, choosing a candidate who won no primaries, would doom the Democrats. You’re welcome to differ.
