Republican presidential candidate Mitt Romney brings his campaign back to Virginia Saturday, and President Obama will counter by opening two more campaign offices in Northern Virginia.

Former Democratic Natinoal Committee chairman and prospective Virginia gubernatorial candidate Terry McAuliffe will open an office in Manassas while state Senator Mark Herring will be on hand to open one in Sterling, according to Obama’s Virginia campaign.

That brings Obama’s total office number to 33 in the Old Dominion. Romney has 28 there.

Romney will be in Manassas Saturday as part of his four-day bus tour through swing states. Gov. Bob McDonnell, a possible vice president pick, will be on hand.
