Mehmet Oz, the Trump-endorsed Republican nominee for U.S. Senate in Pennsylvania, is in a statistical tie with Democrat John Fetterman, the state’s lieutenant governor, according to a poll.

Oz earned the support of 42 percent of likely Pennsylvania voters in the most recent Insider Advantage poll. On the other hand, Fetterman finished just above Oz, coming in at 45 percent.

However, the race is in a statistical deadlock because Fetterman’s narrow advantage is within the poll’s ±4.2 percent margin of error.
