No question that goodpolitical humor and satire is most needed. It's been my feeling that you have to have a backbone of steel to do it however,... by that I mean you are trusting an audience to be up on the news and perhaps at least read one newspaper in the past month! Sometimes it seems that's too much to ask. ;)
Under stand that in making lite of politics you are asking people to be willing to laugh at themselves and their choices (always daunting) and so in that you will be dividing your audience.
