LINCOLN, Neb. (AP) — Nebraska’s top election official says turnout for the primary topped 25 percent, and the percentage will grow once all provisional ballots are counted. Secretary of State John Gale said Wednesday he was pleasantly surprised by the number of registered voters who showed up at the polls. Preliminary figures show 24 counties had at least 35 percent turnout. Boone County had the highest, with nearly 60 percent of registered voters casting a ballot. Gale predicted a very high turnout for the November general election, which will include the presidential contest and a nationally watched U.S. Senate race between Democrat Bob Kerrey and Republican Deb Fischer.
