George Eichhorn conceded the GOP Senate primary on Friday, clearing the way for little-known Christopher Reed of Marion to get walloped by Tom Harkin this November.

It had to hurt for Eichhorn. Not only did Reed win by less than 1 percent of the vote, he only barely crossed the 35 percent threshold. If no candidate had won 35 percent of the vote, the Iowa Republican Party’s state convention would have selected the nominee. With his background in the state legislature, Eichhorn would have been the favorite to win among the GOP’s state delegates.

I’m guessing Harkin will spend a lot of time this fall campaigning on behalf of other Iowa Democrats.
