A Republican senator appears to have called President Obama “stupid” over his recent comments on the Supreme Court’s heath care case.

Sen. Chuck Grassley, R-Iowa, employing the unique writing style he uses on Twitter, sent out this message yesterday: “Constituents askd why i am not outraged at PresO attack on supreme court independence. Bcause Am ppl r not stupid as this x prof of con law.”

That last line translated: “Because American people are not stupid as this ex-professor of constitutional law.”
