I actually kinda thought/hoped that Joe would do that... if he'd been in his right mind.
If any Democrat did this I would vote for him or her in a heartbeat.
In retrospect, Obama (who I voted for) was far more a centrist than today's Dems... and Clinton (who I voted for twice) was a goddam right winger.
Sadly, moderates from both parties have been exiled from the political system.
A house divided cannot stand.
