Miller (D-Calvert) and O’Malley (D) are co-hosts of a fundraiser in the District on Monday for Earl Ray Tomblin, the acting governor of West Virginia, who is seeking to hang on to the job in a special election next month.

The West Virginia race will be the first gubernatorial contest to be decided since O’Malley ascended to DGA chairman in December. Tomblin held a lead of more than 30 percentage points over Republican businessman Bill Maloney in the spring, but that margin had dwindled to 6 points in a recent poll.

The race is one of four for governor on the ballot this year. Republicans are heavily favored in Louisiana and Mississippi, while the Democrat is leading in Kentucky.

Monday’s fundraiser is being held at McGuireWoods Consulting, a public affairs firm on K Street. L.F. Payne, the firm’s president and a former congressman from Virginia, is listed as a co-host on the invitation, along with O’Malley and Miller. The “suggested contribution” is $500.

Miller, Maryland’s longest-serving Senate president, came to know Tomblin during his tenure as West Virginia’s longest-serving Senate president, an aide said.
