What media bias?

Hat tip to RCP. Initially, the AP headline read as follows: "GOP Gains Ground In Battle For Congress." Evidently, someone in the AP newsroom bitchslapped the rookie who allowed that headline to get through. The headline was subsequently changed to read "Poll Shows GOP Not Making Its Case", though the content of the story didn't change.

As RCP notes:

So, sometime between roughly 6:30 am and 10:26 am the Associated Press switched the header on the story about its own poll results from being pro-GOP to something decidedly more negative.

Nope...no liberal media bias!
