Consider this rhetorical challenge:
Name an R leader since Eisenhower on whom the MSM did not crap.
John McCain? While he was celebrated by the MSM for his Trump-Hatred, he was demonized as Hitlerian after he won the 2008 R Presidential nomination.
Mitt Romney? He was demonized as Hitlerian after he won the 2012 R Presidential nomination.
Even Susan Collins and Lisa Murkowski get demonized during election cycles to remind them not to get too uppity-conservativy.
Everett Dirksen? Maybe, though I wasn't yet following politics and news.
