When I first heard this idea, it sounded plausible. It seems more likely every day.
Hilliary can't win a Presidential election. She's proved that twice.
Biden can't either, but he's got a better chance than Clinton. Biden might be going senile, but he has more personality than a cardboard cutout.
Whenever Clinton speaks, she poisons anything she supports.
So, watch for it.
I feel the same way you do about the possibility of Hillary, but the DNC knows that Bernie is unelectable so Joe is the most palatable turd remaining.
