It's easy to forget that the tea party movement is still less than 5 years old. Its successes include the 2010 midterm elections, when it helped the GOP win back the U.S. House.
It was once again a noisy and resurgent player in American politics in 2013. But that doesn't mean it was a year of victories: The movement's campaign to repeal Obamacare failed, and public approval hit near-record lows after the tea party forced a partial government shutdown. Even tea party events aren't as large as they once were.
