No liberal bias here. Nope. No sir.

Dispute it all you want. It is a matter of record that Democrat presidents get a bigger pass from the media than Republican ones. For just one example, take a look at David Frum's article on liberal bias in economic coverage. Here's a tidbit:

In 1996, Bill Clinton ran for reelection as president. The U.S. economy was doing well at the time: unemployment down to 5.2%, inflation under control at 3%, and overall growth at 2.2%. And the press reported all this good news: According to the 2004 MRC study, 85% of all major economic stories on the economy in the summer of 1996 were positive.

Eight years later, George W. Bush was running for re-election as president. The U.S. economy in 2004 did much better than in 1996: The economy grew at a 3.9% pace, while unemployment and inflation roughly matched their 1996 levels (5.4% and 2.7% respectively). Yet this time, 77% of all major media economic coverage was negative.

There's more where that came from. Take a look at the article.
