The 2008 Democratic Primary was, by and large, a bitter fight between Barack Obama and Hillary Clinton for the nomination. Ultimately, Obama won out, and eventually became President. IOTL, Clinton was obviously considered a serious contender for the VP slot, yet was apparently never even vetted by the Obama camp for the position. But what if for one reason or another, Obama had decided to choose Hillary Clinton, rather than Joe Biden, as his Vice President? Would this ticket have been successful in 2008? What about 2012? And if they had won in at least 2008, what, if anything, would change about the administration with Clinton in the #2 spot?
