Oz jumps ahead of Fetterman overnight in major election forecast of Senate race

Republican "slightly favored" to win Senate election.
Lt. Gov. John Fetterman and GOP Senate Candidate Mehmet Oz

Republican Pennsylvania Senate hopeful Mehmet Oz jumped ahead of Democratic challenger John Fetterman literally overnight in trackings of a major election forecaster, a sign that the GOP candidate has a better-than-average shot of winning the contentious race. 

Oz is now "slightly favored" to win the Senate race, FiveThirtyEight said on Monday, with the election analyst giving Oz a 57/43 chance of winning the race. 

Those numbers flip-flopped literally overnight from Sunday into Monday, with Fetterman being given a 54/46 edge on Sunday before the projection reversed on Monday. 

Polling collected by FiveThirtyEight over the last several months shows a definite shift in Oz's favor: From August through most of October, most polls heavily favored Fetterman, sometimes with strong double-digit leads; starting in late October after the two held their one and only campaign debate, polls began shifting in Oz's favor. 

The debate was wildly seen as a disaster for Fetterman, who frequently had trouble speaking and articulating his thoughts. The state lieutenant governor suffered a stroke earlier in the year and has been public about his struggles with recovering from it. 

RealClearPolitics likewise predicts that Oz will take the Senate seat, establishing Pennsylvania as a "GOP hold." The race is meant to secure the seat being vacated by GOP Sen. Pat Toomey, who is retiring in January.
