CNN's front page link to Jack Cafferty's blog from 9/14/2011: Should President Obama consider not running for re-election? And some of the evidence that Cafferty cites to support his point of view: "A new CNN poll shows Obama receiving the highest disapproval rating of his presidency at 55%." George Bush's highest disapproval rating: 69%! This is beyond biased. For context, check out Gallup poll data on average presidential approval ratings...
You'll see that a 45% approval rating isn't all that unusual. This isn't news. This is like shouting "fire!" in a crowded theater. Write CNN. Tell them you're sick of the way they slant the news.
