Yes they likely know they have no chance to overturn the election in PA and WI and only a snowballs chance in hell of overturning MI.
You are right that this is just to make his win illegitimate to the street mob and be a rallying cry for 2018, even if they dont challenge. With Trump publicly saying he won’t investigate Hillary further, I doubt Hillary will authorize any challenge now. She knows she would not succeed and Trump then would publicly reverse himself saying the investigation into her misconduct resumes 1/20/17.
I wouldn’t be surprised that this may be the reason Trump is calling off the dogs from Hillary in exchange for her not making trouble via challenges in these states.
Trump lost Washington State, New Hampshire, Rhode Island and Nevada by small margins. If you recount all the narrow Hillary losses, you recount all the narrow Hillary wins, as well. At some point, you have to conclude that they are not seeking justice though the heavens shake, but shaking the heavens and using justice as a pretext.
They will always make trouble. We never win by being nice to them.
Same thing with amnesty. Conventional gop-e thinking was we needed to be for it in order to win hispanics. All it did was hurt the gop with other voters and the hispanics voted for the dems anyway since they’d get amnesty plus more govt benefits
