Republicans are not totally to blame.  Key word is 'totally'.  Members of the house are re-elected every two years.  As such they are running continually for re-election.  1/3 of the senate likewise.  They know that 25 percent, or so, of republicans are adamant Trump supporters and it would be at their peril to counter Trump.  That is a misfortune for all of us.  What does it take fully knowing that TRUMP is mentally and emotionally unfit to hold office.  If one is to ask a Creationist what would it take to realize the Bible is not literal.  The answer is nothing.  So it is with a Trump supporter.  Nothing possibly would deter them from believing his lies.  Trump must be taken to task and examined by an exogenous entity such as the American Psychiatry Association.  He is THAT disturbed.  Take courage, take heart.  This means journalists, cable news, all who hold this nation more dear than party politcs and religious persuasions.
