Romney said at the time. "Those are up to the people of Ohio. But I certainly support the efforts of the governor to reign in the scale of government. I am not terribly familiar with the two ballot initiatives. But I am certainly supportive of the Republican Party's efforts here."

Gov. Rick Perry's presidential campaign immediately attacked the former Massachusetts governor for "finger-in-the-wind politics."

At an event with Virginia Gov. Bob McDonnell (R) on Wednesday, Romney didn't miss a second opportunity to prove he was for curbing worker rights.

"I'm sorry if a created any confusion in that regard," he said. "I fully support Gov. Kasich's -- I think it's called Question 2 in Ohio. Fully support that."

"I don't even know what Question 1 is. If there is a Question 1, I don't know what that one is. So with regards to Question 2, which is the collective bargaining question, I am 110 percent behind Gov. Kasich in support of that question."
