Some other news. Yesterday was primary day in Nebraska and voters delivered a surprise. Both parties were choosing candidates for a Senate race.
DAVID GREENE, HOST:
And the Republican primary started with a pattern that has become familiar. The leading candidate was backed by traditional Republican leaders but was challenged by another candidate with Tea Party support and a lot of outside money.
INSKEEP: It became a fierce campaign, but here's where the pattern was broken. Neither contender won.
Republicans hope to wrest control of the U.S. Senate in November from the majority Democrats, who have twice as many seats to defend this year. One state where the GOP has high hopes is Nebraska, where two-term incumbent Ben Nelson, a Democrat, is retiring. Voters from both parties will select their nominees Tuesday, and the Republican winner is likely to face a familiar face: former Democratic Sen. Bob Kerrey.
