Affiliate Marketing Secrets

Several of the Democrats I’ve recently talked to about politics have been statists. As a libertarian, I try to find points of agreement with people to keep hostility to a minimum. When I said I thought things like ending US military involvement in the middle east and ending drug prohibition were good ideas, they disagreed with me. Two people even disagreed that the federal government should mandate that gay marriage be legal. At first I was surprised, and then I realized that Obama is a Democrat and holds very similar, non-liberal views.
Has anyone else noticed this? I know there are still real liberals like Jared Polis in the party, but they seem to be a dying breed. Is the Democratic party trending toward a new ideological position? Are actual liberals still comfortable affiliating with it?
Please don’t try to extract an argument from my question; there is none. It’s a real question that has been inspired by my personal observations.
