Why does it seem that people are reluctant to make fun of President Obama?

I am not real old, but I am old enough to be aware of an almost sacred American tradition, whereby comedians who are skillful impressionists imitate the president’s voice and mannerisms in a fashion that makes the president seem like a comical character (an appropriate thing to do, in my opinion, to every president). I have heard recordings of people doing JFK and Lyndon Johnson. Nixon was clearly a target. On reruns of Saturday Night Live, Chevy Chase makes fun of Gerald Ford falling down and I saw a terrific SNL rerun of Dan Akroyd doing Jimmy Carter. Lots of people did a great Ronald Reagan. The guy on SNL did a fabulous Bush 41. Even I could do Bill Clinton’s Arkansas drawl. Bush 44’s ridiculous malapropisms were a great target. And Obama has his own little quirks-“Let me be clear….” and the way he rotates left and right when he speaks etc. But I do not see people imitating him and making fun of him the way that it occured in the past. I admit, I do not watch much TV anymore, so maybe I am missing something. But I just do not get the impression (no pun intended) that people are making fun of this guy the way that they should. Have people lost their sense of humor? Have people forgotten that a president is just another shabby politician in a black suit and red tie? (That would be sad and dangerous). Help me out please.
