The co-chairwoman of the Republican National Committee said in Wisconsin that voters there "might not be as sharp as a knife."
"It's not going to be an easy election, it's a close election," said Sharon Day, the co-chairwoman, while speaking at a GOP field office in Waukesha, Wis., according to the Milwaukee Journal Sentinel. "Like I said, much closer than I can even understand why.
"I don't want to say anything about your Wisconsin voters but, some of them might not be as sharp as a knife," she added.
Day was born in Texas, and has lived in Florida for decades. The chairman of the RNC, Reince Priebus, has long lived in Wisconsin.
Wisconsin Gov. Scott Walker (R) is locked in a tight race with Democratic businesswoman Mary Burke. The latest Marquette University poll finds the two tied at 47 percent.
Walker achieved national prominence during his clashes with public sector unions in 2011. He is widely considered to be a possible 2016 presidential candidate if he can win reelection this year.
