Ah yes, the Delaware Senator, sure to appeal to Southern voters.
Meanwhile, in reality, Biden was a moderate Democrat chosen because of his 30+ years of experience in the Senate countering what was seen as a weakness of Obama, which was his lack of experience, having only just started his first term as Senator a couple of years earlier after coming from the state legislature. An experienced and well liked statesman at Obama's side completed the ticket.
That's moderate by the way, not conservative. As in the middle of the the Democratic caucus, not the US at large. There were far more conservative Dem Senators in the Dem caucus of 2008, several of them did damage to the ACA, like Lieberman. Biden ran to the left of Obama on some issues, in fact. You're absolutely full of it and it's clear you know nothing about Biden beyond tweets you saw with roses attached.
