Barack Obama leads John McCain by five percentage points in Pennsylvania for the second month in a row. Both candidates have lost some support from a month ago, with the Democrat now favored by 45% while his Republican opponent earns the vote from 40%.

When “leaners” are included, Obama’s lead is down to just three points, 48% to 45%. A month ago, Obama led by six when leaners were included.

The data in Pennsylvania reflects patterns seen elsewhere in recent polling. McCain has more support from Republicans than Obama does from Democrats, and McCain also wins more crossover votes from the other party. The two candidates are even among unaffiliated voters.

Obama wins among younger voters and those who don’t attend church while McCain has a solid lead among senior citizens and regular churchgoers.
