One reason for Bush's choice of running mate, Senator Dan Quayle, was to appeal to a younger generation of Americans identified with the "Reagan Revolution". Quayle's good looks were praised by Senator John McCain: "I can't believe a guy that handsome wouldn't have some impact."
Most men, maybe all, are poor judges of other men's attractiveness. It's not what we usually compete with each other over. We can easily tell who can kick whose ass, but not who the girls will stand extra close to in conversation.
The fact that he doesn't just notice, but verbally ejaculates about Quayle's looks, should have been a tell. Perhaps it just wasn't widely reported. I bet someone at the Republican Convention had a WTF moment, though. After being tipped off by a Trump speech last winter, I looked up old pictures of McCain and determined he indeed has gayface.
Trump has been around these people for so long, often while they were drunk and he was sober, and he has a great memory.
It seems like the '80s saw the infiltration of the Republican Party by the poz squad (Kasich, Hastert, among others). The idea must have been that the Establishment bosses and Wall Street donors could control them by having the ultimate blackmail card. So far, it has worked well for both master and servant.
Now that Trump has no common interest with either side, however, he can turn the closet card against its originators. Either Paul Ryan, Lindsey Graham, et al support Trump's America first movement, or he'll spill the beans. That puts these closeted homos in a bind -- no matter which side they choose to serve, their old master or their new one, the other master will pull the trigger to make good on their threat.
Trump has already mooted the topic of why Graham and McCain are joined at the hip and go everywhere together "like the Bobbsey twins," and has also brought up Huma and Hillary being more than just "friends".
So the Establishment-controlled gays know that at least their new master is willing to pull the trigger, whereas their old master hasn't done so up to this point. My guess is they'll wind up siding with Trump, or at least not obstructing his plans, lest their dirty secrets see the light of day and disgrace them irredeemably with their conservative base.
As in so many other ways, Trump is not building up too much from scratch -- he's simply taking over control of what already exists. He doesn't need his own website, he dominates Twitter. He doesn't found his own TV channel, he dominates the existing networks. He doesn't need millions of dollars of oppo research -- having known the insiders for decades, he's already aware of what skeletons are out there.
Why re-invent the wheel? That would be a far too costly way to win, for the most frugal candidate in our nation's history.
