… why McCain (that’s him in Harrisburg this week) is spending so much time in Pennsylvania, that is, despite polls showing this state is all but out of reach for him.

From The Hill’s Blog Briefing Room:

An internal Barack Obama campaign poll has the Democrat ahead of John McCain by just two percentage points.

WILK radio host Steve Corbett said Tuesday he obtained an Obama campaign e-mail about the internal poll showing a tight race. Pollster.com’s trend line of public Pennsylvania polls has Obama leading McCain 54 percent to 38 percent.

The blog noted later that the poll in question was “apparently from last week. But it may help explain Pennsylvania Gov. Ed Rendell’s (D) call for Obama to campaign more in his state and McCain’s renewed emphasis there.”
