Only Americans think that CNN isn't right of center. Many think the BBC is fairly unbiased, and CNN is definitely well to the right of the BBC.

Another data point: the Democratic party would be considered a centre-right party in most countries.

CNN international is also very different from CNN USA.

CNN international seems to be reading AP press releases. CNN USA is mostly just anchors reading twitter, with the occasional story about how racist and violent the tea party is.
