The Obama-Biden Bid
By the summer of 2008, Obama had secured the presidential nomination in a narrow victory over Clinton. After vetting seven potential candidates, Obama selected Biden to be his vice presidential running mate.
The pair would go on to win the fall general election against Republican Sen. John McCain of Arizona and Alaska Gov. Sarah Palin, and they took office on Tuesday, Jan. 20, 2009. (Joe Raedle, Pixabay)
