There are two political parties in the US, the Democrats and Trump. Despite historically dismal overall approval ratings, ratings among the GOP find Trump to be second only to post 9/11 Dubya in approval from his own party at the 500-day mark.
So no, the notion that Republicans will turn on Trump even should Mueller or the Senate present evidence of conspiracy or worse is ludicrous. They will defend Trump even at the cost of their own livelihoods. The Republican party is nothing more than the racist, misogynist, bigoted cult of personality that worships Trump, and so are all of his voters.
I'm tired of being nice to them. It's only made them love Trump more.
It's time to call these assholes out this November and throw them out of power for good. Get registered, get ready, get friends, get to the polls. At every turn President Obama's open hand was met by fist after fist.
Now it's time to fight.
