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.
If the GOP is stupid enough to nominate Dauphin Jeb, you can bet on it.
