Chris Cillizza reports on The Fix blog that Democratic National Committee Chairman Tim Kaine announced today that he would immediately resign his post to pursue a run for the open Senate seat in Virginia.

“I am writing to let you know that I have just announced my decision to run for the U.S. Senate from the Commonwealth of Virginia in 2012,” Kaine wrote in an e-mail to DNC members today. He called the move “an exciting next chapter for my family and me as I embark down a new path.”

Kaine’s announcement is a major recruiting success for Senate Democrats, who had worked hard to persuade the former Virginia governor to make the run. It also sets up a potential battle of Virginia political titans as Kaine could well face off against former senator George Allen (R) in the general election.

The race is for the seat of Virginia Sen. Jim Webb (D), who is retiring after a single term.
