By Trumpism, they generally mean conservatism, or the only force in any opposition to them and their policy ideas.
America First is Trumpism
Tariffs are Trumpism
Tax Cuts are Trumpism
A border wall is Trumpism
Etc.
It’s just a catch-all for their opposition.
“It’s just a catch-all for their opposition.”
Yes.
Before Trump it was Bushism. They hated Bush as much as Trump.
They hated Dole. Rosie O’Donnell called Bob Dole a fascist in 96, for example.
The Tea Party made them really go crazy because finally there were people who actually believed in conservative principles. They hated fake Rinos just for pretending.
Trump took it even farther.
There is a self-loathing involved in their psychology in the extreme ones.
Trump-ism is patriotism.
