This is one in a pretty long list of Republican US Senate and HOR seats in which the Establshment ceded the election rather than be supportive of a pro-Trump candidate. Roy Moore is in this category. And the HOR? Paul Ryan's last dirty deed for his masters was to hand the majority to the dems.
JMHO
I tend to agree with you, although I find the answer is even simpler. As I posted at FR a lifetime ago the reason The Bolsheviks are winning is because they want to win more than do The Patriots. Our side too often sees politics as at-best a corrupt debate club because we are busy with useful things like faith, family and productivity. The Bolsheviks see it as existentialist theology because they have nothing else transcendent in their lives other than their own sanctimony and nihilism.
We “choose our fights,” they see every conflict as a matter of life-and-death. When you bring a bouquet to any conflict, even if it is a rhetorical one, your odds of success are slim and none.
