Republican presidential candidate Mitt Romney will campaign in Northern Virginia on Wednesday, a day after his second debate with President Barack Obama.

Romney will hold a rally in Leesburg, in the heart of a swing region that could be critical to determining which candidate carries Virginia’s 13 electoral votes. Obama won nearly 54 percent of the vote in fast-growing Loudoun County in 2008. A year later, Republican Bob McDonnell got 61 percent of the vote there in his landslide gubernatorial election.

Romney has made multiple trips to Virginia since his first debate with Obama on Oct 3. He and running mate Paul Ryan appeared at a large rally in Augusta County on Oct. 4 and Romney led a rally in Abingdon on Oct. 5. Last week, Romney made stops in Lexington, Newport News and Chesterfield County.

Ryan will campaign in Lynchburg and Fredericksburg on Tuesday.

Obama spent the weekend in Williamsburg preparing for Tuesday’s debate. He held no public events, but did take a break to greet volunteers at a local campaign office.

Update: Romney’s campaign announced late today that he also will campaign in Chesapeake on Wednesday.
