The Tea Party is an American populist political movement，which is generally recognized as conservative and libertarian，and has sponsored protests and supported political candidates since 2009. It endorses reduced government spending，opposition to taxation in varying degrees，reduction of the national debt and federal budget deficit. And in the end，the movement did what GOP leaders who embraced it had hoped above all：It energized core Republican voters at the grass roots in a way the party’s traditional leaders couldn’t.
