There's a disclaimer at the outset of this movie warning that the content is guaranteed to offend just about everyone. Here in the 21st century, one should heed that warning. There are all kinds of offensive racial and sexual stereotypes that would have naturally raised hackles in 1975, let alone in the present. The movie is about the campaign (fictional) of Linda Lovelace, known mostly for starring in the seminal '70s porn movie Deep Throat, for president of the United States. Lovelace is nominated by a group of six walking caricatures (representing millions of people each), including a really butch lesbian, a really effeminate man, an actual neo-Nazi, a token black, a Chinese man (not played by an Asian, of course), and a Catholic priest. After being convinced by her (literal) Uncle Sam to run for president, Lovelace embarks upon a nationwide tour, giving speeches and hopping into bed with as many helpful young men as possible. Now, in case you're still uncertain about this movie's virtues, there is definitely no reason anyone under 18 should be allowed within 100 yards of the film. There's nudity and sex, although there isn't much violence. But, seriously - she's a porn star playing herself, so there's naturally some softcore scenes thrown in to get the attention of male viewers. If the rampant sex doesn't put you off, then maybe the over-the-top characterizations will. Among the cast are Mickey Dolenz as a near-sighted bus driver, Art Metrano (Police Academy) as a sheikh, Scatman Crothers as a pool hustler named Super Black (!), Kennedy impersonator Vaughn Meader as a lusty preacher, and Joe E. Ross (Car 54, Where Are You?) as a dirty trickster in politics. Like some other movies of the late 60s and early 70s, the major theme here is of chaotic wackiness. As the lead, Lovelace is fine playing herself. There's not much plot, there's a ton of offensive material, and nudity abounds. But if you see it in the right frame of mind, perhaps viewing it as an artifact of its times, this isn't a terrible film. (For a fun bonus, check out all of the protest signs near the beginning of the movie. Pure genius putting the AA people next to the AAA people.)
