(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.
In Nevada, Gov. Jim Gibbons failed to convince Republicans to give him another chance at a four-year term, while a Tea Party-backed candidate won the GOP nod to challenge Senate Majority Leader Harry Reid.
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.
CNN keeps referring to how Halter's campaign was "fueled by unions and liberal activists" while mentioning nothing about how Lincoln's campaign was fueled by corporate interests.
