The real question is why was Rush propping up Rubio.
Rush is no stranger to GOPe. He used to be a rebel with a cause - conservatism.
I think he’s more a global liberal-tarian these days. All the high profile “conservatives” are. They are all owned by the globalist ideology of multi-national corporations.
But conservatives are attached to America’s constitutional ideology and American interest which is in direct conflict with globalism - socially, politically and economically.
