2010 was the year of the Tea Party.
The grassroots conservative political movement made its clout felt the entire year, from the healthcare reform debate to GOP primaries and the general election last month.
In the end, the Tea Party was in many ways a net asset for the GOP as Republicans grabbed control of the House and cut into the Democratic majority in the Senate.
However, there was collateral damage as Rep. Mike Castle (R-Del.) and other Senate GOP hopefuls seen as the party’s best chance of winning general-election races were ousted in primaries. Some blamed Tea Party candidates for costing Republicans a Senate majority to go with their new majority in the House.
