The Lake Woebegone stuff was amusing the first few dozen times (yeah, yeah, children above average), but he needs something new. That tired old "Republicans are evil, while Democrats really care about people" business isn't going to cut it, either.
I gave up on PHC about the time they syndicated.
When Garrison started playing to a national audience, the jokes got watered down, the guests got professional, and all of it started to take itself too seriously.
There's a thread over on the MPR News Forum about whether Garrison should be allowed to say such things on Public Radio - is it appropriate for a tax-supported venue?
My take - get rid of the tax supports, then let him say what he likes.
