Romney to Campaign in PA

Expanding the map:

Mitt Romney is set to make a last-minute campaign stop on Sunday in Pennsylvania, The Daily has learned.

Details are still being determined, but two top Pennsylvania Republican officials and a Romney adviser said a large rally in the vote-rich Philadelphia suburbs is in the works for Sunday. Romney aides confirmed the coming visit after initial publication of this article.

“It’s going to be a huge rally and it’s going to be very successful," one senior level Republican official said.

“They said all along, ‘if you get within a certain margin we’ll consider it,’” another top Republican said. “They said they’d come the final week, and we got there.”

PA hasn't gone Republican for president since 1988, but Tom Smith's Senate candidacy plus Romney's emphasis on Obama's "war on coal" have combined with the unpopularity of ObamaCare to put the state in play. Twenty electoral votes -- two more than Ohio -- are up for grabs. Polls show Romney within about four points and closing.
