Last time he was on target was back when he was a cast member of SNL..and a Liberal. Now he's like you, by the time he gets to the punch line his audience is bored to death.
He is still a liberal, but the definition of that word has changed so much that the people we should consider liberal are now incorrectly called conservative or libertarian.
It is unfortunate that the far left has abrogated the term but certainly not the spirit for they certainly are not for any type of liberty other than the absolute right to infanticide/abortions.
I sometimes listen to Miller's radio show as I drive. He still has some zing, but I wasn't around when he was on SNL so I can't make the comparison.
Hey, my punch lines are rare gems, well worth waiting for! But you do have to put up with the build up to understand them when delivered! Anytime I get right to the joke I get the critics like you on my case saying that it just ain't funny, so subtlety and hidden references have to do.
