The goal of the Tea Party is to reform the Republic party from the ground up. They intend to support candidates who are unlike many current Republican leaders and, you might say, overwhelm the Republican leaders.
They are on record as saying that a third political party would just split the vote.
Yeah, I guess that's why I can't really get behind them. I don't think you can reform something that is as corrupt as the Rebublicans (and Democrats) are. I'd rather see something new started. The way politics are played, you'll get some freshman congressmen voted in that want reform, but they'll be sidelined by the entrenched power brokers until they fall in line with them.
Maybe I'm just too pessimistic for my own good
