Rick Wilson, a Republican consultant for almost 30 years, has a must-read op-ed, titled "If You Work For Trump, It's Time To Quit," in the Washington Post today.

In concludes:

"Sticking with Trump to the bitter end and pretending the unfolding chaos is just “fake news” won’t save your reputation as the walls close in. It won’t ease the judgment of history. It won’t do anything to polish up your future Wikipedia entry. Cutting ties with a man who is destructive to our values, profoundly divisive, contemptuous of the rule of law and incontrovertibly unfit to serve in the highest office in the land just might. Do it now."
