Former Pittsburgh U.S. Attorney Mary Beth Buchanan will decide within the next couple weeks whether she will seek the Republican nomination for a House seat in Western Pennsylvania, the Pittsburgh Tribune-Review reported today.

Buchanan, who served as the Western District of Pennsylvania U.S. Attorney from 2001 until November 2009, told the newspaper that she was “very encouraged” by meetings she had with local Republicans about seeking the 4th District seat just north of Pittsburgh that is held by Rep. Jason Altmire (D-Pa.), who is running for a third term.

“The common message I’ve been hearing, consistently, is that most voters feel the current administration is forcing its agenda and programs on people who don’t want them, who don’t feel like paying for them and who are not willing to leave this tax bill for future generations,” Buchanan told the Tribune-Review.

The ex-U.S. Attorney would likely challenge lawyer Keith Rothfus in the Republican primary, according to the newspaper. Congressional Quarterly rates the district as “likely Democratic” for the 2010 election.

Beaver County GOP Chairman Marty Matthews told the Tribune-Review that Buchanan would face an “uphill battle” if she runs. The former U.S. Attorney has received harsh criticism for her unsuccessful prosecution of former Allegheny County medical examiner Cyril Wecht.

Her office dismissed all charges against the prominent Democratic defendant after a federal judge threw out evidence that he ruled was improperly obtained. Wecht’s supporters accused Buchanan of targeting him because of his politics. And former Attorney General Richard Thornburgh asked Attorney General Eric Holder to discipline Buchanan for “vindictively” suggesting at a news conference that Wecht was guilty, but nothing ever came of the request -– at least publicly.

“Personal opinion, I think if there were another candidate who had the recognition that Mary Beth Buchanan has, it would be the better choice,” Matthews told the newspaper. “It’s the Wecht thing, primarily.”

We reported last week that Buchanan also came out on the losing end of an apparent political skirmish over a rescue mission for 53 Haitian orphans. She was trying to organize efforts to help Haitian children stranded in an orphanage destroyed by this month’s earthquake. But Altmire and Gov. Ed Rendell (D) planned their own rescue mission and kept the Bush U.S. Attorney mostly out of the loop.

Two other former U.S. Attorneys from Pennsylvania who served during the administration of George W. Bush have already declared their candidacies for House seats.

Tom Marino, who was the U.S. Attorney for the Middle District of Pennsylvania from 2002 to October 2007, is running for the seat held by Rep. Chris Carney (D). Patrick Meehan, who led the Eastern District of Pennsylvania U.S. Attorney’s Office from 2001 to 2008, is seeking the seat that is being vacated by Rep. Joe Sestak (D), who is running against Sen. Arlen Specter in the state’s Democratic Senate primary.
