Mitt Romney comes to Virginia Saturday to kick off a bus tour of several swing states.

Gov. Robert F. McDonnell’s (R) office announced Monday that Romney will campaign in Virginia, but provided few details. The office said only that McDonnell, who is often mentioned as a potential vice presidential pick, will join the Republican presidential challenger at unspecified campaign events in the state Saturday.

The Romney campaign confirmed the visit and said that Romney will launch a multi-state bus tour from Virginia. “The Romney Plan For A Stronger Middle Class” bus tour will begin in Virginia and continue to North Carolina, Florida and Ohio. Further details will be announced in coming days, the campaign said.

Romney and President Obama have already spent considerable time and money in the Old Dominion, where a new poll shows the race dead even.

Along with personal appearances by the candidates and their high-profile surrogates, they’ve inundated the state with campaign ads.

Obama campaigned in Leesburg last week and made a two-day swing through the Commonwealth July 13 and 14, in Hampton Roads, Roanoke, Henrico County and Northern Virginia.

Romney had a two-day Virginia tour of his own at the end of June, with stops in Roanoke and Northern Virginia.

The day before Obama came to Henrico, Romney’s campaign dispatched a former New York mayor Rudy Giuliani to attend the grand opening of a campaign office there.

First lady Michelle Obama had been scheduled to appear in Charlottesville and Fredericksburg last week, but canceled because of the movie theater shooting in Colorado the night before.
