One might just as well ask themselves why no Bush supporters ever seem to get around to making films of their own, if he's so bloody popular 'mongst both the hoi and the polloi. Funny, that.
And exactly which of these "accomplishments" is someone -- friend or foe -- supposed to make a feature-length hagiography of? Sticking a firecracker in Iraq's ass just to watch it blow? Running up the deficit? Making sure Paris Hilton doesn't go broke, under the guise of "keeping the economy strong"? Learning how to pronounce "subliminal" and "nuclear"? We're all on the edge of our seat, sweet cheeks.
Most people can't keep pace with inflation and/or gas prices, not to mention that the world order is collapsing around our ears while Junior learns how to work the remote, seven years into the game. Please be assured of my sincerity that people are welcome to make films about those subjects (in lieu of, say, Fred Claus) any day of the week.
