I think that's a little bit over overstatement. The old USSR is gone, and Russia is casting bells for churches and commissioning them these days, so... forever?.... hardly. Blink of an eye and things can change.

California is gone forever, and cannot change in a “blink of an eye”>
California did not become permanently liberal because the voters are going through a cycle, it went blue because the original voters have been replaced by permanent liberal voters who have no cultural or historical interest in our past America and identity, and reason for existence and concepts of freedom and individuality and social conservatism.
There is no cycle coming up, these are new people, a different people, than those WASPs that ran LA and California and made up the electorate.
