President Obama arrives in the state Tuesday as part of three-day North Carolina and Virginia bus tour to talk about the economy, but it’s not clear how many Virginia Democrats will be with him.

As we reported today, Democratic state legislators are none too eager to support Obama, let alone be seen with him.

The state’s top Democrats will be not be around, either.

Sens. Jim Webb and Mark Warner will be in Washington, where Congress is in session. (Warner is holding his first online forum today. He will start doling out video responses to questions at 2 p.m.)

Tim Kaine, former governor and Democratic National Committee chairman, is spending the day in Northern Virginia, in part to help legislative candidates who are on the ballot next month. Kaine, now a candidate for the U.S. Senate next year, appeared with Obama at the University of Richmond in August.

“We fully expect him to attend other events with the president throughout this election cycle, just as we expect our opponent will appear with the eventual Republican nominee for president,’’ Kaine spokeswoman Brandi Hoffine said.

The White House would not release a list of elected Democrats who would be with Obama in Virginia.

The president began his bus tour Monday in North Carolina and will continue Tuesday and Wednesday in Virginia — two critical swing states he carried in 2008 that remain just as important in 2012.

The White House had considered stops in Danville, Newport News, Charlottesville and Fredericksburg. But prominent Democrats in Virginia — where Obama’s approval rating hovers around 50 percent — encouraged the White House to alter the schedule so he would no longer visit districts where members of his party were involved in tight races.

Instead, Obama will speak at a high school in Emporia on Tuesday and at Langley Air Force Base in Hampton and a fire station in Chesterfield County, outside Richmond, on Wednesday. He will be joined by first lady Michelle Obama in Hampton. All three events are closed to the public.
