Affiliate Marketing Secrets

I’m not saying all members of the Tea Party make this claim but MANY members rant about it. Also MANY Christians that are not affiliated with the Tea Party make the same claim.
In reality those weren’t the Founding Fathers intentions.
Please read The Treaty of Tripoli, Article 11 which states:
“As the Government of the United States of America is not, in any sense, founded on the Christian religion,—as it has in itself no character of enmity against the laws, religion, or tranquility, of Mussulmen,—and as the said States never entered into any war or act of hostility against any Mahometan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries”.http://memory.loc.gov/cgi-bin/ampage?col…

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.
