Do those categorized as "liberal" actually disagree with Tea Party principles?

Some of the basic principles of the Tea Party movement can be found here. When I go through them, I can find very, very few that I fundamentally disagree with as government principles. I also see a lot of Tea Party representatives as shown in media declaring things that I do fundamentally disagree with.

At its essence, the Tea Party movement may be the closest thing to a political revolution that we may witness in a two-party system. I find people reacting against it are mostly, to be simple myself, liberal. But although I am classified as liberal politically, it is because of mostly conservative principles (personal liberty, personal responsibility, fiscal responsibility, small government (or rather, a right-sized government), etc.).

Are there principles that make it impossible for liberals to support the Tea Party movement? Are liberals doing themselves a disservice by not supporting the Tea Party movement? Are liberals missing out on an opportunity for real government reform by not establishing a voice for themselves in the Tea Party movement?

Thoughts?
