I think the segment of his supporters that are not complete and total morons are waiting for, like many, the Mueller investigation to conclude.
And they don't mind if House Republicans obstruct that effort, threaten to impeach Rosenstein, parade out nonsense attacks on the DOJ, etc...their patriotism and sense of decency is, how did that guy say it...in escrow right now. They would love to see the investigation end, so they would not have to consider what we all know is coming after both the social media Russians, and the hacking Russians, are now all laid out as establishing a criminal conspiracy against the United States.
The Trump ass-kissing of Putin has been going on since the beginning, this recent Helsinki display was just a lot of it, all in front of Putin on the world stage. Trump did his normal betray America stuff, but then added on top the traitorous idea of trading Americans for Russians, having Putin help us with cyber security, and of course his secret back room meeting with an agenda we know nothing about.
That's the pinnacle of what he's done so far in furthering the Putin agenda, but his base was never concerned about that. What's trading America if in return we get to treat immigrants like ****, strip the EPA, pack the courts, and cut taxes and increase the deficit for the next president to unravel?
I suspect we'll see enough people change their tune when Mueller concludes. If it's not allowed to conclude, there will be a fight at many levels of government and likely from public outrage. I hope it doesn't come to that.
