Women have been at the forefront in results from a dozen US primaries, where voters like those pictured have been picking Democratic and Republican candidates for November's mid-term elections.
In California, former eBay boss Meg Whitman became the first woman to be Republican candidate for governor. The billionaire, who spent $70m (£48m) of her own money on the campaign, will face a veteran Democrat in the race to succeed Arnold Schwarzenegger.
Another former Silicon Valley boss, Carly Fiorina of Hewlett-Packard, won California's Republican nomination for the US Senate. She will challenge Democratic Senator Barbara Boxer in November's mid-terms.
One of the most high-profile races was among Democrats in Arkansas, where two-term Senator Blanche Lincoln beat Bill Halter, confounding pundits who predicted she would lose because of widespread anti-incumbent feeling.
South Carolina Republican Nikki Haley - campaigning to be the state's first female governor - won a place in a run-off vote, during an ugly race in which she strenuously denied claims she'd had two extra-marital affairs.
In Nevada, Republicans chose Tea Party-backed Sharron Angle as their mid-term candidate to face Senate Majority Leader Harry Reid, a Democrat whose popularity in his home state has nosedived.
Ms Angle beat one-time favourite Sue Lowden, a casino owner who was ridiculed for suggesting cash-strapped consumers use chickens to barter over their health bill, like in the "olden days".
