Answer
Charlie Crist received 30% of the votes in the U.S. Senate race in 2010. This was a significant drop from his 48% win in the 2006 gubernatorial election. Crist was a popular governor, but he lost some support after he switched parties from Republican to Democrat in 2010. Crist's opponent, Marco Rubio, was a rising star in the Republican Party and he was able to capitalize on Crist's unpopularity.
