SUWANEE, Ga.—Herman Cain may use numbers a lot in his public speeches, but sometimes his math doesn’t add up.

 The former GOP presidential hopeful, campaigning on behalf of former House speaker Newt Gingrich (R-Ga.), told a crowd at Collins Hill High School here that when it came to voters, “50 percent of the American people do fall in the category of either stupid or ignorant as to what’s going on in this country.”

As the audience applauded, the former CEO of Godfather’s Pizza kept going.

“Some people don’t like me because I tell the truth like it is,” Cain said. “Those of us who are informed outnumber the stupid people, but not if we stay home.”

No word on how the informed portion of the electorate outnumbers the stupid part if it’s a 50-50 split.
