True, and I still do not understand this at all. Some of this obsequious behavior must come from fear of Trump's influence on the core Republican right-wing nutter voter base, a fear that perhaps might diminish a bit now after the midterms have demonstrated that Trump's endorsement is not always a plus.
I can only imagine what it must feel like be Cruz, Graham, etc. and every day have to keep smiling, nodding, and praising Trump despite all the insults and debasement. True of his cabinet too. How many showers must one take to feel clean again? It would be soul destroying, if one had a soul. Fortunately Cruz, Graham, etc. long ago sold or rented theirs...
