The Republicans had chances to repudiate Trump for over a year as Trump made fun of women, calling them names, made fun of people, apin them with disabilities, aping Clinton when she had pneumonia, openly advocating for racist policies. But they never did, they went along with Trump. Goes to show what kind of opportunists the Republicans are. And now they are rats jumping off the Titanic just before they hit the iceberg they've been watching for a couple hours. Trump is a sexual predator, and Republican leadership is, wink wink, condoning it, McConnell and his corrupt ilk for sale. 
Even though Clinton is similarly ethically deficient, it looks like she will win by default. And this is coming from a undeclared voter.
