Classic liberalism is what I learned about in college (think John Locke--I was a huge fan, have to re-read his stuff sometime soon, quite frankly) and we, of all people, should not be using the word "liberal" as a pejorative. The word has taken just as much of a beating as the word "conservative."
True conservatives and classic liberals have far more in common than neoconservatives (established) and "neoliberals" (weaseling their way in.)
Look up classic liberalism and see what it's about. Classic liberals are our allies. I'm not sure if Kucinich is close to being one or not, but he's not all bad--so far as I can tell. He needs to get on board with HR 1207 though.
I was reading up on David Souter's resignation today and, as I am wont to do, I always dig a little deeper. He's maligned as a "liberal" because he didn't fall in lock-step with the religious right's expectations. But this guy is truly a thoughtful individual with a good understanding of the Constitution (noto bene--I've only read two chapters of a biography and read about 12 articles, so I know I could be wrong.)
He seems to take a very technical position, which I respect, because he's technical about the Constitution and generally treats it if it were set in stone. And that's something I think that most all of us can support, no matter whether that leads us to a "liberal" conclusion or a "conservative" conclusion.
Isn't that what it's all about?
