They just can't seem to get enough of this one. It looks like another Republican is still pushing the idea that China is drilling for oil in deep ocean waters near Cuba -- Rep. Sam Graves of Missouri is continuing to push it even after big-name Republicans like GOP Sen. Mel Martinez and even Dick Cheney have disavowed it, and his staff is refusing to offer any retraction of his statement.

The Missouri Democrats are sending around this YouTube of Graves, who is facing a tough challenge from former Kansas City Mayor Kay Barnes, pushing the China-Cuba story at local campaign events:

Graves campaign spokesman Jason Klindt is sticking to the story for now.

"We have one newspaper that says China is drilling and one that says China is not drilling," Klindt told Election Central via e-mail. "If it turns out to be verified as inaccurate, he will certainly let his constituents know."

Like Jean Schmidt before him, Klindt cited a source that didn't actually appear to back up his point. Klindt referred us to a 2006 New York Times article that only said China was planning to drill there. Since that story was published, as GOP Sen. Mel Martinez laid out on the Senate floor, China is only drilling along shoreline areas of Cuba at this juncture.
