When President Obama crosses the Potomac into Virginia Tuesday morning to talk about reining in the nation’s escalating debt, which Democrats will be standing with him?

Not Tim Kaine.

Word is the former governor, former chairman of the Democratic National Committee chairman and friend of the president will be campaigning for U.S. Senate — but in another part of the state.

The state’s current U.S. senators aren’t around either.

Sen. Mark “Mr. Gang of Six himself” Warner has a packed schedule in Hampton Roads. Sen. Jim Webb is on a two-week trip to Korea, Vietnam, Japan and Guam.

Rep. Jim Moran’s office tells us he has a prior commitment. We never heard back from Rep. Bobby Scott, who is mulling a run against Kaine for senate in 2012.

Even Brian Moran, chairman of the Democratic Party of Virginia, won’t be there. He is sending his wife, Karyn, in his place.

But Rep. Gerry Connolly will be standing by his president. Obama will, after all, be in Connolly’s district when he heads to the Northern Virginia Community College in Annandale.

Who else will be there? We tried to find out, but with no success. The state party told us to check in with Organizing for America — which referred us to the DNC, which did not know. Guess we’ll find out later this morning.

UPDATED, 11:20 A.M.: The White House indicates that Falls Church Mayor Nader Baroukh is in attendance. Sources on the ground tell us that Sens. Dave Marsden and George Barker, both of Fairfax; Del. Mark Keam of Fairfax, Del. Charniele Herring of Alexandria and former delegate Steve Shannon of Fairfax are also there.
