Today's Social Liberal Is Tomorrow's Social Conservative

Cato's Will Wilkinson argues that younger, more socially liberal voters are the prime target for a future "liberaltarian" left-liberal fusion:

Generally speaking, social policy has grown less restrictive throughout American history. People are are currently 70 years old are far more liberal on, say, the question of women's suffrage than were people fifty years their senior. But women's suffrage is settled fact, and no longer exerts any electoral impact. Several decades from now, we may well be looking at an even more liberal or left-wing social issue landscape. Today's young voters are much less freaked out about an African-American president than are today's old voters. But what about fifty years from now when the Democrats have nominated a transgendered Presidential candidate?

And then there are those of us who are already decades ahead of the curve.

I've already written a full length screenplay in which a transgender character becomes a head of state by popular acclaim.

On the whole even at the age of 50 I still find the moral and ethical qualms of most of those 30 years my junior to be pretty cautious and reactionary. My biggest fear is that I may actually live long enough to see the pendulum swing back the other way. In which case I guess I'm well and truly done for!
