I don't know about here, but for the time being, the arse has fallen out of the US impressionist comedy scene. It's not so easy to satirize a regime when one doesn't know who's in charge. When the new guy gets in, for the first time in a long time, there's a distinct absence of public cynicism about the leadership.
Without cynicism, there's not a lot of point trying to do do satire. Everyone loved Tina Fey's impersonation of Sarah Palin but I don't think people want to see an impersonation of Obama. Not for a while, anyway.
By the way - if Hummers asks you if you've seen his "Elephant", I'd advise you to run. Don't walk...
