That would be the, uh, very rural farm vote, according to the Washington Times:
One can’t get much more grass roots than this: Sarah Palin is the keynote speaker Thursday at an agricultural “field day” near Baltic, S.D. — population 1,090 — situated on the scenic banks of the Big Sioux River in the eastern corner of the state. The former vice presidential candidate/potential U.S. Senate hopeful is going no-frills, however, journeying to the heartland accompanied by her youngest daughter.
“It’s an honor to get to travel with my entourage, er, that would be Piper, to be with those who are feeding the nation,” Mrs. Palin said in a Facebook post about the one-day event.
The goal of it all, say organizers Darren and Brian Hefty, who are both rural media moguls and farmers, is to showcase the best ways to raise crops. There’s a free lunch, a free supper and complimentary snack goodies. There’s a corn panel, a soybean panel, and forums on drainage laws, crops insurance and grain marketing. The kids’ area is crowded with games and giant inflatable toys.
