Truth.

Krugman, via Kos:

There’s no conflict between catering to the Democratic base and staking out positions that can win in the 2008 election, because the things the base wants — an end to the Iraq war, a guarantee of health insurance for all — are also things that the country as a whole supports. The only risk the party now faces is excessive caution on the part of its politicians.

Actually, that's been truer than most folks think for longer than most will admit. After all, we're mainstream, they're extreme.
