Oddly, Obama hasn’t mentioned his previous support for Occupy Wall Street.

SPRINGFIELD, Ohio – Seven months after the Republican presidential primaries ended, the tea party is back.

But it’s not GOP nominee Mitt Romney invoking the tea party, it’s President Obama accusing the former Massachusetts governor of being a shill for the conservative wing of the Republican Party.

At three events Thursday and two on Friday, Obama said that Romney is “pledging to rubber-stamp the tea party agenda in Congress.”

“That’s not change,” he added at a high school gymnasium here. “That’s what we need to change.”

The tea party, a regular feature of GOP primary debates, has long been absent from Romney’s stump rhetoric since he claimed the nomination. Obama also has rarely mentioned it aloud.
