Comedians with a lack of imagination?

Kyle Smith:

Why comedians and ‘SNL’ are shielding President Obama

...
Got that? The charter Choom Ganger, confessed eater of dog and snorter of coke. The doofus who thinks the language spoken by Austrians is “Austrian,” that you pronounce the p in “corpsman” and that ATMs are the reason why job growth is sluggish. The egomaniac who gave the queen of England an iPod loaded with his own speeches and said he was better at everything than the people who work for him. The empty suit with so little real-world knowledge that he referred to his brief stint working for an ordinary profit-seeking company as time “behind enemy lines.” The phony who tells everyone he’s from Chicago, though he didn’t live there until his 20s, and lets you know that he’s talking to people he believes to be stupid by droppin’ his g’s. The world-saving Kal-El from a distant solar system who told us he’d heal the planet and cause the oceans to stop rising. The guy who shared a middle name with one of the most hated dictators on earth. 

Nope, nothing there to mock. No way to get a grip on this polished, oiled obsidian. So comedy writers didn’t and mostly still don’t. Jim Downey isn’t in dereliction of his comedy duty to take down the high and the mighty, or so he begs you to think. He’s just too obtuse to see Scrooge McDuck quantities of comedy gold when they’re sitting right in front of him. Did Sarah Pallin lack for material to lampoon when she blasted away at Obama in her 2008 convention speech?
...

There is much more.

They are liberals who can't see how funny liberalism as as practiced by Obama.  They should try harder.
