Virginia Attorney Patrick Lewis (D), who had initiated a 2010 campaign against Rep. Frank Wolf (R), won’t be continuing his effort in the 10th district.

Lewis’ decision to shutter an exploratory committee he formed last month leaves Richard Anthony and architect Dennis Findley as the Democrats challenging Wolf, who is serving his 15th term in a district that includes some northern Virginia suburbs of Washington, D.C.

An e-mail to Lewis’ campaign wasn’t immediately returned, and his campaign Web site wasn’t online Tuesday afternoon.

Wolf won by 20 percentage points in 2008, even as his district backed Barack Obama (D) over Sen. John McCain (R-Ariz.) for president. But the district trended Republican in the Nov. 3 gubernatorial election, giving Republican Bob McDonnell 61 percent of the vote.
