Rush Limbaugh had some harsh words for Mitt Romney on Tuesday, over the candidate's response to the Supreme Court's immigration ruling.

The court recently determined that certain parts of Arizona's controversial immigration policy are unconstitutional. Romney was criticized for his late and vague response to the decision. He said that he "would have preferred to see the Supreme Court give more latitude to the states."

On Tuesday, Limbaugh expressed his frustration with Romney's reaction, calling it "tepid" and a "red flag" for the campaign. The radio host declared that "Mitt Romney blew it" with his response.

"The Romney campaign was not ready for primetime on this illegal immigration Arizona decision," Limbaugh insisted, noting that it was the first time he thought that in a while. He added that he thought the campaign has been doing a "superb job" rapidly responding to new developments.

He argued that immigration was too important an issue for Romney to hold back on. "You can't live off of Obama's gaffes, like the economy's doing fine... forever," he said. "You gotta be a proud, eloquent defender of the Constitution when your opponent is stomping all over it."
