On radio station WTOP Tuesday, Virginia Gov. Bob McDonnell (R) all but ruled out the possibility of becoming the vice presidential choice of presumptive GOP nominee Mitt Romney.

"I am not being vetted by his campaign," he told the radio audience. 

That doesn't completely shut the door if the Romney campaign came calling. McDonnell has not said he would say "no" to the VP slot if it were offered.

The popular Republican governor, who received 59 percent of the vote before he was sworn in as the 71st head of the Commonwealth in 2010, said he plans to serve out his term, which ends in January 2014.

McDonnell became chairman of the Republican Governors Association in 2011 and has campaigned for Romney in Virginia, as well as in Southern primary states.

President Obama and Romney, a former governor of Massachusetts, will be battling for voters in Virginia in the presidential election set for Nov. 6. On Sunday, PBS NewsHour political editor Christina Bellantoni characterized Virginia as "the battleground of all battlegrounds."

Even if he is not vetted for VP, McDonnell said he plans to help Romney win his state. "But I'm going to do everything I can to help him in Virginia," he told NBC's Chuck Todd this week.

An NBC/Marist poll last week showed Obama with a 4-point lead over Romney in Virginia. The poll asked how Obama would do in Virginia in a match-up between the Obama/Biden ticket and Romney and McDonnell as a team. The poll said Obama would get 46 percent of the vote, and Romney 44 percent of the vote.
