I find there is too much out there, and there is little in the way of a critical analysis to help decide what to listen to.
However I would recommend "whack my bush" funny satire with impressions of Bush, Blair, Arnie & a few others. If you are familiar with an old English TV show 'Spitting Image' it's a bit like that for radio.

Any other recommendations?
