You can get real, objective US political coverage from PBS, and the BBC. It's tough to find it elsewhere. Smaller newspapers frequently do a good job of keeping local politicians honest, but the situation has to get really bad before large media outlets will appropriately skewer a president or Speaker of the House, say.
The British press is much less forbearing with their politicians. I've seen editorials and cartoons that are downright nasty. While I despise politics in general, the US media could use some really brave editors and columnists who are brave enough to call the president a fool if that's the case. You should see what the Brits say about Prince Charles. It's ugly. We need some of that incisive commentary on our side of the pond.
