Paul:  well put... The GOP leadership and down-ballot candidates have hung the "lepers' bell" around Trump's neck.  He's become the most toxic Presidential candidate in history.  When your VP running-mate openly snubs you, you know you're in real trouble.  Pence, it seems, can count to 4 and would rather be a viable GOP candidate in 2020 than disappear down the drain with Trump.  In all fairness, who can blame him?  

Other GOP leaders look at the House and, especially, the Senate and say, with justification, "Geez, we could lose it all!!"  Down-ballot candidates, many of whom, up to now, have tried to "straddle the fence"...neither endorsing or opposing Trump.. have openly disavowed his candidacy...again, who can blame them?  

The GOP made a horrible decision in nominating Trump..Actually, they made an earlier horrible decision in "selling out" to the hardcore right wing of the party.  Those chickens are now coming home to roost...and it's not pretty.....
