Pollsters dumbfounded by Trump

In another act of political magic, Trump managed to flip his favorability rating from negative to positive in one poll during the span of a month — a feat that Monmouth University’s Patrick Murray called “astounding.”

“That defies any rule in presidential politics that I’ve ever seen,” Murray, the director Monmouth’s Polling Institute, told The Hill.

Trump’s favorability rose from 20 percent to 52 percent among Republican voters between July and August, Monmouth found.

While a later CNN/ORC poll did not find a similar shift in Trump’s favorability, the Monmouth data was yet another sign that he is a candidate to be reckoned with.

“Throw out the rulebook when it comes to Trump, that’s not even in the parameters of what we see as unusual,” Murray said.
