Democratic Senator Blanche Lincoln won a high-profile battle in Arkansas to claim the nomination, defying critics who expected her to lose. In Nevada, ultra-conservative Sharron Angle was chosen to front the Republican ticket. She will face Democrat and Senate Majority Leader Harry Reid, whose popularity has waned in recent months. And in South Carolina, Republican Nikki Haley won a place in a tight contest. Also campaigning to be the state's first female governor, she was endorsed by former vice-presidential candidate Sarah Palin.
