Pennsylvania Senate candidates John Fetterman and Mehmet Oz squared off Tuesday night in their race’s first and only debate, a bruising encounter shaped in part by the Democrat’s lingering communication difficulties following a stroke. 

The event came exactly two weeks before an election in the pivotal contest, which could determine the partisan tilt of the U.S. Senate. 

Though Fetterman held a sizable polling lead over his GOP rival through the summer, Oz has been whittling away at this advantage as Election Day approaches, and recent surveys have suggested the candidates are now neck-and-neck.

The hour-long debate, which took place in Harrisburg, covered topics including crime, the economy and abortion and gave voters the opportunity to evaluate Fetterman’s recovery from the life-threatening stroke he suffered earlier this year.
