RICHMOND, Va. (AP) — Don’t look for Democrats in fiercely contested Virginia legislative elections to join President Barack Obama as he brings his campaign-style American Jobs Act bus tour to three cities there.

For that matter, don’t expect Tim Kaine, the former Democratic National Committee chairman and Virginia’s governor two years ago, to join his old ally either.

But one statewide elected official will join Obama: Republican Gov. Bob McDonnell, a GOP vice presidential prospect and a sharp, frequent critic of the Obama White House.

Obama targeted North Carolina and Virginia, both swing states he won in 2008 that are vital to his re-election next year, for his second bus excursion aimed at pressuring Congress to enact pieces of his $447 billion jobs bill.

The president will appear at Greensville County High School in Emporia on Tuesday afternoon, a military base in Hampton Wednesday morning, and at a suburban Richmond firehouse Wednesday afternoon before flying back to Washington.

Republicans say Democrats, particularly Senate incumbents trying to preserve a narrow majority in the Nov. 8 elections, are so afraid to embrace the unpopular president that Obama changed his Virginia itinerary to avoid stops near targeted Democrats.

A senior Virginia Democrat told The Associated Press on Oct. 7 that the president’s itinerary at the time called for stops in Danville, Charlottesville, Newport News and Fredericksburg.

Virginia GOP Chairman Pat Mullins contends the White House changed course because most of those cities are in or near districts where Democratic incumbents battling for political survival are distancing themselves from the unpopular president.
