Stage is set

The country music is on the P.A. and (by now) most of the seats above are filled for Mitt Romney's appearance today at the Sauereisen plant in O'Hara today at noon. PA12 GOP congressional candidate Keith Rothfus is working the crowd.

Those are bags of acidproof concrete, affixed with "Made in the USA" stickers, behind the podium.

U.S. Rep. Tim Murphy, R-Upper St. Clair, and the state GOP chair Rob Gleason are also here.

UPDATE: Romney's primate meeting with Rick Santorum this morning was at the offices of Santorum's longtime political consultant John Brabender in Mt. Washington. (CNN)
