(CNN) - Arkansas Sen. Blanche Lincoln won the Democratic primary Tuesday, beating back a challenge from Lt. Gov. Bill Halter, whose campaign was fueled by unions and liberal activists.

Voters in 12 states held primary elections Tuesday night, but the outcomes of two contests in South Carolina will be delayed by another two weeks. A runoff will be held on June 22 for the Republican gubernatorial nomination as well as for a GOP congressional seat in the northern part of the state.

The Republican gubernatorial contest captured national attention because of accusations of extramarital affairs.
The candidates are vying to succeed scandal-plagued Gov. Mark Sanford, a fellow Republican. A year after Sanford made national news for disappearing and then admitting to an affair with a woman from Argentina, allegations of infidelity surrounded state lawmaker Nikki Haley.
Washington (CNN) - When President Obama throws out the first pitch at the Washington Nationals' season opener on Monday, he will kick off not only a new baseball season but also a new round of fundraisers at Nationals Park.
Though Obama won't be raising any cash himself on game day, his appearance will be the backdrop for at least one ballpark fundraiser Monday, the first of what Nationals President Stan Kasten hopes will be many political events held at the stadium this season.
Since Nationals Park first opened in March 2008, Kasten has actively encouraged political operatives of all ideological stripes to hold their fundraisers and receptions at the ballpark, as opposed to more conventional venues such as restaurants or hotel ballrooms.
(CNN) - Craig Newmark, founder of Craigslist and a customer-service guru, was riding on a public train in San Francisco, California, recently when something common but annoying occurred: The railcar filled with people and became uncomfortably hot.
If the inconvenience had happened a few years ago, Newmark said he would have just gone on with his day - maybe complaining about the temperature to a friend.
But this was 2009, the age of mobile technology, so Newmark pulled out his iPhone, snapped a photo of the train car and, using an app called "SeeClickFix," zapped an on-the-go complaint, complete with GPS coordinates, straight to City Hall.
"A week or so later I got an e-mail back saying, 'Hey, we know about the problem and we're going to be taking some measures to address it,' " he said.

NEW YORK (CNN) - Actor and political activist Ron Silver, who played a recurring role in TV's presidential drama "The West Wing," and who also let his political views play out in real life, died Sunday after a two-year battle with esophageal cancer, according to a colleague.
Robin L. Bronk, executive director of The Creative Coalition, said Silver, a New York native, died in his sleep with his family around him.
"Nothing could hold Ron back, not even a debilitating illness. His contributions as an artist and activist will never be forgotten," said Bronk, who runs an organization founded in 1989 by Silver, actor Christopher Reeve and other prominent figures in the arts as a political advocacy organization for the entertainment industry.
