Washington (CNN) - If Rep. Steve Driehaus didn't already face an extremely difficult re-election bid, a move Monday by national Democrats is making the freshman's task even tougher.
The Democratic Congressional Campaign Committee is pulling the plug on television commercials for Driehaus after this week. A Democratic source confirms reports earlier Monday by the Rothenberg Political Report and by the National Journal's Political Hotline that the DCCC has canceled its media buys after this week. But the DCCC will still finance get out the vote efforts in the district.
Two years ago Driehaus beat seven-term Republican Rep. Steve Chabot by five points in a district that President Barack Obama captured by 11 points.
This year Chabot is running to reclaim his old seat and both the Rothenberg Political Report and the Cook Political Report, two of the top non-partisan political handicappers, rate the race as "Lean Republican."
"It is difficult to read the cancellations as anything other than the Committee's decision to write off the Driehaus race. The DCCC could reverse course and re-purchase the time, of course, but it would then pay a higher rate," says Rothenberg.
As the deadline nears for canceling ad-time that's already reserved, the big question is if other Democrats will find their support waning.
Ohio's first congressional district includes Cincinnati, as well as some very conservative suburbs to the west and north of the city, which have been tough territory for Democrats. Driehaus' vote in favor of the health care reform law has hurt him with many of his suburban constituents.
The National Republican Congressional Committee says that as of now, they are not dropping their ad buys in the district.
