It is always true follow the money. GOPe made Rush and he owes.
Conservative listeners made Rush.
Conservative intellectuals or think tanks used to offer agendas for conservative politicians and citizens. They have been taken over by the thinking and agenda or ideology of globalism.
I think globalization has seeped in a bit at a time, killing off conservative thinking and culture. I don’t think Rush or any of his globalist listeners made the decision to stab conservatives in the back or to end conservatism.
Globalization has a social agenda (amoral, atheist borderless/nationless globe) with an economic system the same. It hates conservativism because conservatives are concerned about the power, issues and conditions of the nation and it’s CITIZENS. It is concerned about moral and ethical issues and healthy/fruitful/successful lifestyles from a Western cultural pov.
