Perhaps it's fitting that the state that kept everyone up late last night, waiting for results, was Ohio. It's a swing state, and it seems every four years, in the fall, Ohio becomes the center of attention in a presidential election.
This year, as NPR's Tamara Keith reports, it just happened a little earlier.
TAMARA KEITH, BYLINE: Talk to Ohio voters - Republicans and Democrats alike - and there's one issue that rises above all the others.

Unless you grow cotton, corn or soybeans for a living, it's hard to appreciate just how amazing and wonderful it seemed, 15 years ago, when Roundup-tolerant crops hit the market. I've seen crusty farmers turn giddy just talking about it.
Every May, Russia displays its military might in a parade on Victory Day, commemorating the surrender of the Nazis to the Soviet Union in World War II.
The marching men and rolling tanks put on an impressive show, but Russia's military, and especially its defense industry, has fallen on hard times.
