Rep. Tom Marino (R-Pa.) may face a Tea Party challenge to his reelection: Bradford County, Pa., Commissioner Doug McLinko (R) is seriously weighing a bid.

"I'm not declaring I'm going to run, but I'm certainly seriously looking at it," he told PoliticsPA on Tuesday.

McLinko declined to attack Marino in the interview, though he made it clear he'd run to the right of the incumbent in a possible primary.

"I supported him the first time he ran. It's just evident we’re cut from a different cloth. At this point, I'm not going to take any shots at him," he said. "The direction our party's going, they're lost. Being a conservative is not a label you give yourself. It’s a label that's given to you. And you look at Washington today, the way the federal government is being run from the Republican side, it is in disarray."

Marino has a fairly conservative voting record, though on the deep-pocketed Club for Growth's scorecard, he has just a 61 percent lifetime score, putting him in the bottom third of Republicans in Congress. If the group goes after Marino, that could be problematic for his campaign.
