Tea Party candidate Ron Johnson has defeated incumbent Democrat Russ Feingold to become the next senator of Wisconsin.
Feingold was considered one of the most bi-partisan guys in the Senate, teaming up with the likes of John McCain to author campaign finance reform, the McCain-Feingold Act.
But it was his unwavering support for President Obama on issues such as healthcare that ultimately led to his defeat.
Taking over is Johnson, a political novice and successful businessman.
