Here's the thing.
There are two posits:
A) Trump did not want to win.
B) Trump colluded with the Russians.
If B is false, then A can very well be true.
I have never been convinced that Trump personally colluded with the Russians. I have little doubt some of his team did, but not Trump himself.
At most, Trump was informed of the upcoming meeting between his son and the Russians, and that dirt on Hillary was being offered. But Trump himself was not an active colluder, if that's a word.
That in no way removes my certainty that Trump is completely infatuated with the KGB thug.
In fact, it is that infatuation which led Putin to try to get his fan boi elected.
During the 1992 campaign, I often got the feeling Bush, Sr. did not want to win re-election. I had the same feeling about Trump.
In Bush, Sr.'s case, I think he was just tired and wanted to quit. With Trump, it felt like this was just a big lark to him.
