As the days go on, there’s a fatalistic, going-through-the motions aspect to much of “90 Days.” And on and on it goes — with more in the way of juvenile insults than Obamaphiles engaged in back in the days of Hope and roses. “[S]hort of electing a born-again monkey with downs syndrome [sic], anyone who replaced Bush would be considered ‘a change,’ ” writes comedian David Cross. Obama’s “not Romney. He plays basketball. Romney sucks at basketball. He doesn’t believe in wearing magical underwear, like Romney does,” comments comedian Reggie Watts. Director David Lynch notes that if you scramble the GOP candidate’s last name, you get “R MONEY. I believe Mitt Romney wants to get his Mitts on R Money. He would like to get it and divide it up with his friends, the Big Money Bunch.” No wonder “Twin Peaks” didn’t make any sense.

The incoherence, petulance and desperation of “90 Days” documents the decline of a presidential cult. That’s a welcome development: Partisan fervor and cults of personality are the enemies of sober judgment. It’s skepticism, not passion, we need when evaluating potential presidents, lest we get swept away and wind up ashamed of ourselves in the morning.

In one of “90 Days'” rare flashes of common sense, author and screenwriter Sherman Alexie observes that “the liberal messiah does not exist.” True — and a good thing, too.
