Look up the Craig Spence male prostitution/blackmail ring. GHW Bush's #2 man on WH Personnel was caught up in it. Those who aren't closeted gays have adulterous affairs that can be used to blackmail them. And now "homophobia" is a grave character flaw for a Republican. It's probably too late.
That's gonna' mean, of course, that people like Newt Gingrich are going to have to stay out of Republican party internal politics.
