Three Democrats from West Virginia, including first-term Sen. Joe Manchin, are skipping the Democratic National Convention in Charlotte, N.C. this September, where President Obama will formally receive the party’s presidential nomination.

The West Virginia Democratic Party told reporters Monday that in addition to Manchin, Gov. Earl Ray Tomblin and Rep. Nick Rahall do not plan to join West Virginia’s delegation. State Party Chair Larry Puccio said Sen. Jay Rockefeller will attend and will serve as the group’s honorary chair.

Mr. Obama is unpopular in the state and lost 41 percent of the West Virginia primary vote to a convicted felon. Manchin — who faces his own re-election battle this year — has said he’s not sure he’ll vote for Mr. Obama.
