Congressional Leadership Fund plans to parachute into the southwestern Pennsylvania seat and deploy its voter turnout operation to bolster Republican nominee Rick Saccone, a state representative, in the March 13 contest. The race was triggered last fall after Republican Tim Murphy was forced to resign from Congress amid a sex scandal.
