Pennsylvania: Clinton 40, Trump 32, Johnson 14, Stein 5

The new Muhlenberg survey suggests that Trump has some work to do if he’s going to tip Pennsylvania’s 20 electoral votes to a Republican for the first time since 1988.

A critical challenge lies within his own party: 71 percent of Republicans say they’re backing Trump, while 10 percent back Clinton and 19 percent are unsure. Among Democrats, 81 percent are for Clinton, 11 percent are for Trump and 9 percent are uncertain.

Independents lean toward Clinton, 42 percent to 33 percent, and one-quarter are undecided.

“Trump is able to attract some Democrats, but he can’t lose the amount of Republicans that this poll is showing and win the state,” Borick said. “It’s not mathematically possible.”
