Scott Brown was the front runner the moment he entered this race -- his third Senate run in five years -- and he topped a field that included former U.S. Senator Bob Smith and former State Senator Jim Rubens by about 20 points.
In his victory speech, Brown targeted President Obama as much as incumbent Democrat Jeanne Shaheen -- their race is one of a handful that will decide which party controls the Senate.
"We need change and the problem is a vote for my opponent will change nothing. Nobody in the Senate is more invested in the policies and the failures of the President than Senator Shaheen."
Outside groups have already plowed big money into this contest, as have the candidates. $16 million has been spent so far and this race is expected to become the most expensive in state history.
