Las Vegas, Nevada (CNN) - A conservative Republican candidate, whose critics said was too outside the mainstream to win, has won Nevada's Republican Senate primary.
Sharron Angle beat Republican establishment favorite Sue Lowden and businessman Danny Tarkanian in a race that had grown increasingly bitter in the final days.
In the latest results, Angle won 38.6%, Lowden came in second place with 27.9% and Tarkanian placed third at 22.6%.
Angle will challenge Senate Majority Leader Harry Reid.
Angle was supported by the Club for Growth, an anti-tax fiscally conservative political group, and the Tea Party Express, which vows to spend an additional $1 million or more in support of Angle to defeat Reid. The Tea Party Express says it has already spent $550,000 in support of Angle.
