There were a few posts about this town hall meeting here at FR, but they didnt turn up in a search. if i find them i'll post the link. The group at the town hall wasn't 'led' by John and Ken,. They are just vocal critics who reported on it. Yes, they have the leading talk show on a 50k watt station (KFI is the #1 station in America); so of course that gets the story (whatevere story KFI deems fit to publcize) great exposure.
I will agree with you that they're 'yahoos'! ;-) But they do some great work.
They are by no means 'leaders' of this movement/sentiment; they're actually just reporting on it and are an outlet for southern californians
