The Communist states that remain are either small and weak, or crazy and dysfunctional (N Korea).

Conservatives are convinced Liberals are at best fools or dupes of foreign ideologies, or, at worst, traitors. They fantasize of returning to some idyllic, Utopian past (before the Liberals took over) when America was truly free.

Liberals think Conservatives are, either mindless fanatics or cynical and opportunist hypocrites. They fantasize America as inevitably progressing to some glorious Utopian future which is being resisted and obstructed by the Conservatives.

Conservatives are in love with an America that never existed, Liberals are obsessed with an America that can never be. Both blame the other for their troubles.

In a way, they're both right. The truth, as always, is somewhere between the two extremes.
