Sen. John Cornyn (R-Texas), who is up for reelection in a state where polls show Trump and Biden in a dead heat, said polls are likely off.

“I think they’re in all likelihood underreporting support for the president. That’s what we saw in 2016,” he said, noting that most polls still accurately predicted the popular vote…

Senate Finance Committee Chairman Chuck Grassley (R-Iowa) also voiced skepticism about a recent poll showing Biden and Trump in a dead heat in Iowa, a state the president carried by 9 points in 2016.

“Because of previous years’ poll being wrong, I think it’s legitimate to question. I don’t know whether they’re accurate or not,” he said.
