I remember conservatives openly wishing/praying/speculating upon RBG's death before it happened. Way before.
I distinctly remember one prominent conservative here on Imgflip doing just that, but not gonna put him on blast here.
Beyond mere political differences it's apparent RBG was a good person, Rush wasn't.

The Left equivalent of Rush Limbaugh dying would be, I dunno, Howard Stern or Bill Maher or Keith Olbermann. I really don't think you'd see too many liberals shedding too many tears over them.
Most of us gravitate toward real news, not political infotainment.
