Obama picks Bayh as VP in 2008: What happens in 2016 and 2020?

[Mister Mets]

Assuming Obama wins reelection, you would probably have a more crowded field in 2016, just because it's the Vice President versus Hillary, so there's less pressure for others to stay out. She would remain the frontrunner, given her advantages (ties to Bill Clinton, desire for first female President, approval rating as Secretary of State) and the lack of a constituency for Bayh.
