Chuck Schumer at a campaign event for Lew Fidler

Senator Chuck Schumer had some fun the other day when he "mistakenly" confused the "Buffett Rule," President Barack Obama's tax proposal that the wealthy pay at least the same tax rate as the middle class, with presidential candidate Mitt Romney.

"So, it's a priority for us to act on some kind of Romney—I mean, Buffett Rule," he joked.

Mr. Romney, of course, is on the defense over his tax rate -- he only pays about a 14 percent tax rate on the tens of millions of dollars he earns each year. Mr. Schumer, who heads the Senate Democrats messaging efforts, was more than happy to remind voters of Mr. Romney's tax situation.

Politicker caught up to Mr. Schumer at a campaign event this afternoon and asked if "the Romney Rule" would be a phrase that would see continued use.

"The Romney—I mean, Buffett rule, is very important," he succinctly responded with a smile.
