Kaine Checks Out Butter Cow and Chomps Pork Chop in Secret Stop to State Fair

DES MOINES, Iowa -- Tim Kaine is in Iowa for the first time since securing the Democratic Vice Presidential nomination.

It comes as a new poll shows the Democratic and Republican tickets virtually tied in the state.

The Quinnipiac University Poll has Hillary Clinton leading Donald Trump by three points, 47 to 44.

In other swing states, like Colorado and Virginia, Clinton is leading by double digits. Kaine started his day in Cedar Rapids with a campaign event at Kirkwood Community College.

The campaign kept his second event a secret. Kaine eventually showed up at the Iowa State Fair, a traditional stop for candidates. Kaine spent about an hour touring the famous Butter Cow and pork tent, typical appearances for candidates.

Kaine stood by Agriculture Secretary Tom Vilsack, Iowa's former two-term governor. Vilsack escorted Kaine during his visit. Both said they expected the presidential race to be close. With their mouths full of pork chops, both men talked about what could have made for an awkward appearance: both were among Clinton's finalists to become her running mate.

Vilsack said of Clinton's pick of Kaine, "She made the right choice."

"She had an embarrassment of riches," Kaine responded, "And I'm humbled to be on the ticket."

Kaine praised Vilsack as he talked about working hard until election day. "It's going to take us making the case every day," Kaine said. "And I'm standing with the expert here (Vilsack)...close, going to be close. Run like the underdog."
