Donald Trump’s troubles in Pennsylvania are hurting Sen. Pat Toomey’s re-election odds.

At least that’s the conclusion of Stu Rothenberg and Nathan Gonzales, who are moving the PA-Sen seat from “Toss-Up/Tilt Republican”

“Pennsylvania is another state where the weight of Trump is hurting Republicans down the ballot,” Gonzalez writes. “A recent handful of public polls show Trump losing the Keystone State to Clinton by close to double digits and Democratic challenger Katie McGinty with a narrow edge over GOP Sen. Pat Toomey.”

“It will be another couple of weeks before we know whether it is a permanent shift in the dynamic of the race, but the seat is extremely vulnerable and could be the one that puts Democrats over the top,” he concludes. “Ratings change from Toss-Up/Tilt Republican to Pure Toss-Up.”

Senator Toomey is seeking a second term against Democratic nominee Katie McGinty. The U.S. Senate is currently comprised of 54 Republicans 46 Democrats. The GOP is defending 24 seats while the Dems control just 10 of the seats up for grabs.
