To some, 1/4 of the country supporting the Tea Party movement may not seem like much. But, look at the larger picture. The movement is only one year old. It is gaining momentum, while poll numbers for the Democratic Party, Republcan Party, and President Obama are falling. More Americans support the efforts of the Tea Party than the efforts of Congress. Tea Party members represent a silent majority of the people who are no longer willing to stand by while elected officials corrupt our government. They want to restore principles that have been forgotten. Who could disagree with this?
With that said, if the Tea Party simply endorses the Republican party or becomes a third party then they lose credibility. The significance of the movement is to promote principles, not a party.
