If the Clinton flame-out continues, Biden will announce that he will run for a single term, thereby continuing Obama’s legacy and providing a launching pad for the first woman and (fake) Native American president.
I’d take 2:1 on the nomination working out this way and 4:1 on its success.
I think you've nailed it. It will be interesting to see how Hillary and Biden campaign against one another. She can't be too critical of the Obama administration's record, since she was a key player herself. Biden, on the other hand, won't pull his punches when attacking Hillary. He loves to shoot off his mouth without thinking first about what he's saying. The low information voters will still get their chance to help "make history" by voting for a Biden/Warren ticket, but I think mainstream America will view them as weak candidates. The Republicans have a great chance to really bury the Democratic Party. Let's hope they don't once again snatch defeat from the jaws of victory.
