Pennsylvania Republican U.S. Senate  candidate Dave McCormick is closing the gap against Sen. Bob Casey (D-PA), according to a poll released on Thursday.

The most recent Emerson College/The Hill poll found Casey is leading McCormick by 48 to 44 percent, with eight percent undecided.

Casey’s lead against McCormick has dropped two points from his six-percent lead in the June Emerson College/The Hill survey.

ABC27 reported:

Mark Harris, a strategist for McCormick’s Senate campaign to oust Casey this November, found that Kamala Harris and her backing of “San Francisco liberal policies is a toxic brand for Pennsylvania Democrats including weak Bob Casey.”

The McCormick memo stated, “In the days to come our campaign will release a raft of targeted digital, mail, and television advertising to drive home this message. All Pennsylvanians will be fully informed on the failure of the Biden-Harris-Casey agenda and will have a clear choice.”
