I think that this phrase -
"messiah-like adoration"
is a sign of two things: fear, and envy.
Fear that so many Dems have a candidate that they can get behind and get excited about.
Envy that you have nothing even close to it on the Republican side.
We all understand what it is; it's a dig, and an example of whistling past the graveyard, all wrapped up into one condescending little package.
One thing that I do find funny: the term is often used, as you have, to describe 'irrationality' or behavior which doesn't seem to recognize logic. I think it's odd that a group of people who so stridently work to protect people's right to do
actual worship would use the term in that way, as I doubt you would like to hear your belief in God (or whatever) be termed 'irrational'
