Sounds sorta familiar, doesn't it? Pantsuit went that route in 2016. It didn't work then and it sure as heck won't work now.
Biden entered the presidential race in April as a household name who spent eight years as Barack Obama's vice president and decades as a senator from Delaware. Also like Clinton, Biden repeatedly invokes Barack Obama on the campaign trail and his role in the Obama administration. He's promising to build on the battered foundation of the Obama years — particularly with his proposal to shore up the Affordable Care Act. His status as the former VP and Obama's "best friend" has created an aura of inevitability around his candidacy, which consistently leads the pack in national polls.
Which brings up the question: if Joltin' Joe is Barry's best friend, where's Barry now? You'd think he'd be out there praising his best friend, but nope - it's crickets. It's probably because Barry realizes that he wouldn't be able to use "I" and "me" so often if he actually had to support his best friend.
Then too, there's the age factor: Joe's a 76 year-old lifer politician. I don't think Bernie's a threat to him, as he's ready for a wheelchair as well. Pocahontas, however, may well appeal to the dumber younger demographic among Democratics.
So far, Joe's nomination doesn't seem particularly inevitable.
