The state Democratic Party said Obama will headline a Sept. 21 rally in Philadelphia to boost the re-election campaigns of Democratic U.S. Sen. Bob Casey and Democratic Gov. Tom Wolf, but also other down-ballot races that Democrats are contesting.

In the Philadelphia area alone, Democrats are hoping to flip four U.S. House seats and more than a dozen state legislative seats that will be on the Nov. 6 general election ballots.
