Liberalism is like herpes.

Everyone says "I'm not a liberal," right before they spout the liberal line.

It's like a person with herpes. "I don't have herpes." Then they give you herpes.

Then the herpes goes away, and over time people forget how bad it is (see Carter).

When it returns, then everyone goes, "Christ, this sucks!" (see Obama)

Liberalism, like herpes, is incurable, and can only be suppressed. But sadly, it must be allowed to reappear just to remind everyone how absolutely awful it can be.

Common sense is the Valtrex!
