“Though I believe I can win the Democratic nomination and the general election, a winning campaign would require me to devote all of my time for the next 14 months to that campaign," Scott said, according to The Associated Press. "This would mean that my work on issues critical to Virginians and other Americans would have to be postponed."

Scott's decision clears the way for Kaine to gain the Democratic nomination. He is expected to face former Virginia Sen. George Allen (R) in the general election.

The race to succeed retiring Sen. Jim Webb (D-Va.) will be one of the most competitive races in 2012.
