If Russia actually has video of Trump doing something that Trump does not want the American public to see, my bet would be on it being something financial or political — some sort of meeting Trump had while in Russia that either makes it clear to anyone that money is absolutely the only thing he cares about, or where he made statements that sound (or are) traitorous.
The only way I can imagine Trump caring about a sex tape involving him and Russian prostitutes would be if one of them was clearly very very young, or if it showed Trump himself at least partially undressed. He has always thought of himself as God’s gift to women, and if the Kremlin had video of Trump where he looked like a pasty-white old man who eats too much junk food and gets too little exercise (which is what he is), Trump would really not want that getting out. His supporters, even the rabid-right self-proclaimed Christians, will dismiss or forgive just about anything in the way of tawdry sex, except if it involved a child. Or they’d think that it was just good computer graphics or video editing to be blamed on Obama, Hillary, the CIA, Putin, whoever - or they’ll just refuse to watch it. As I’m sure Putin has top-notch computer people available to him who could produce very convincing video of anybody having sex with anything, given a little time, I’m not sure what it would take to convince me, and I’m predisposed to believe almost anything negative about Donald Trump.
Unlike his new BFF Vlad, there are no photos anywhere that show Trump without a shirt. How could he keep up his macho playboy self-image if he had to admit that he is not a hunk, and that women who are attracted to him are actually attracted to his money, not his body? (Heaven knows it ain’t his charming personality.) Yeah, outward appearance is a really poor way to judge someone’s worth, male or female — but it seems to be what Donald Trump has done all his life. It’s very obvious as far as how he relates to women, but have you noticed that Trump’s vice president, cabinet picks and staff are almost all shorter than he is? When his weight would have pushed him into the “obese” range on body mass index charts, he chose to lie about it by having his doctor add an inch to his reported height.
There is of course a question about how many Trump supporters would care about video showing Trump saying unpatriotic, irreligious, or flat out traitorous things, or perhaps admitting to large-scale tax evasion or other illegal activity, but certainly some of them would and the Republican establishment would, and the Republicans who control Congress might actually think they had to follow up on it.
Or is the whole issue of Trump being compromised perhaps really just a Russian ruse to discredit democracy and the US election system? Did the Kremlin leak the information to a known former spy, hoping it would get back and damage the whole idea of government by the people?
