Potential GOP vice presidential candidates
The South Dakota senator was reportedly among those considered for the vice presidency in 2008. He could offer Romney geographical balance, and was an active campaigner for the candidate in Iowa - a potential 2012 swing state.
Thune identifies himself as an evangelical Christian and also buttresses Romney's example of making a second run for the presidency: Thune ran for the US Senate in 2002 and lost by just 524 votes. Two years later, he ran again and knocked off then-Senate Minority Leader Tom Daschle.
