for starters, Watergate was 30 years ago, not 20.
And no, people don't think "watergate happened so this is what I'll do" but their entire cultural conception is informed by the implications of the scandal.
And I don't know what Utah news is like then, but when Watergate comes up, it's rarely "I wonder who deep throat was" in any serious discussion around here. Y'know, where it happened, and where most of the national news happens. When it comes up in a serious discussion, it's about what it means for the history and future of the presidency and thus the nation.
JP: In 1974 Richard Nixon was running for re-election. People associated with his campaign staff, probably with his knowledge (though this is not proven and Nixon was pardoned by his successor to the presidency), broke into the opposing party's campaign headquarters and stole information.
Deputy Directory Felts of the FBI, going by the moniker "Deep Throat" approached reporters Bob Woodward and Carl Bernstein and gave them information to break the story and report on it. THrough their reporting, the scandal came to light, leading to Nixon's resignation (before he could be impeached) and, in part, the cultural attitude in the US of extreme mistrust of politicians and distaste for the government.
(there are obviously many other factors in the formation of that attitude, and it obviously wasn't a brand new attitude then, nor unique to the US, but it was a landmark event that has shaped American attitude and history since)
Deep Throat was known only by his alias till yesterday, I think. I'm not sure when the story on his ID broke.
BUt rest assured that "Deep Throat" was not the only poorly chosen moniker of the time. Nixon's re-election was headed by the "Committee to Re-Elect the President," or in short form, CREEP.
