I’m nearly certain it is true that Russia has dirt on him. But serious question: what possible dirt on trump could even slightly alter his base in the United States? I’m not convinced anything could. They could have videos of him raping an entire kindergarten class and his cult wouldn’t care. So at this point, what power does Putin actually hold? Trump (in theory) could tell Putin to fuck off and that would be the end of it.
I think it’s admiration and not blackmail that keeps trump sucking Putin’s dick. I think Trump looks at Russia and wishes he could have the same unchecked power that Putin has and so he looks up to him.
Here is the link to the report. It wasn’t in the article.
