I don’t believe that. I believe things go in circles, and there will be a conservative President again, in response to the obscene liberalism going on now. 2016 would have been the natural conservative cycle, but Trump co-opted it. He got the conservative vote but didn’t rule like one. Things like the debt and another real war will eventually force reality back on us.
We may not mean the same thing by “conservativism”.
There are forms of conservatism which abhor individualism/libertarianism. Adopting a system of “every man for himself” while being ruled by a powerful elite that was very effective at joint action has led to disaster.
To “conserve” or better, to recover what has been lost, is going to require very powerful common action to uproot and then to disempower our rulers, claiming our rights set forth in the Declaration of Independence.
National Review and the Heritage Foundation are not going to get the job done.
