I saw the film the other night, and while they comment in passing that there do seem to be a lot of gays in Washington D.C. and a lot more gay staffers in politics than in the general population, this is not necessarily true of the legislators themselves—at least that is not what the film-makers claim.
The documentary is about a group of activists who are outing homosexual politicians who attempt to conceal their homosexuality by very vehemently anti-gay public positions and voting records. Most of them, not surprisingly, were Republicans. One thing they make pretty clear is that gay’s worst enemies are self-loathing closeted homosexuals who “run with the hare and hunt with the hounds” as the Australians put it. J. Edgar Hoover and Roy Cohen (McCarthy’s chief hatchet man) are cases in point.
It is possible, even likely, that homosexuals are disproportionately represented in staff positions, since they can work long hours unencumbered by the demands of family, but even if there are many of them and they are in key positions, the don’t seem to have all that much influence in terms of advancing gay rights.
James Galbraith in The Predator State and Thomas Frank in The Wrecking Crew both argue that there is a particular mindset among Republicans and conservative Democrats that the rules don’t apply to them. So, there may be something about power that potentiates deviance. If you think you are on the side of God and the angels, then whatever you do is okay—but not when the other guy does it. You see this in spades in the three C Street Republicans who were caught cheating on their spouses and putting their mistresses’ family members on the payroll to shut them up, etc. as cases in point. They were all up in arms when Clinton got his cigar smoked on company time; but they don’t practice what they preach.
I think it might be easier for Democrats to admit to minor sexual deviance since they don’t hold themselves out to be, and nobody expects them to be, holier than thou.
