As the nominee in waiting, Sen. John McCain has had the luxury of campaigning around the country for the Nov. 4 election -- while Sen. Barack Obama and Sen. Hillary Rodham Clinton battle for the Democratic nomination in the next states and territories on the nomination schedule.

That has changed some lately, with Obama all but assured of the nomination and trying on the role of the presumptive nominee.

Even so, McCain has already campaigned in places like Youngstown, which figures to be a Democratic stronghold.

On Friday, he campaigns in Pennsylvania, but he won't be anywhere near Erie.

He'll be in Pipersville. If that draws a blank, like it did for me, the town is in Bucks County in the eastern part of the state.
