MADISON, Wis. - Mitt Romney's grandchildren have been getting an up-close look at the political process, but at least one - 4-year-old Nate - seems to have had enough of the long, drawn-out campaign.

"Nate, the first thing he said when he saw me was, 'Have you beat Barack Obama yet?' That's our 4-year-old," Romney said today, as he, his wife Ann and three of his 18 grandchildren - Nick, Chloe and Parker - visited with reporters on the back of his tour bus.

"Not yet, hoping to do that," Romney said with a smile, before heading back to his seat.

During the visit, Romney asked the kids what their favorite part of the campaign trail is, and the answers ranged from the big jar of peanut M and M's to the cushy couches on the campaign bus.

Romney then re-told the story of Parker's crazy hair day - when he made a Mohawk with egg whites and Elmer's glue.

"Well we just flew over Lake Michigan, Chicago and were headed to Wisconsin," Romney said.

Asked about what it was like to sit in a 51-year-old Rambler today, which he did at his Troy, Ohio, event Romney said it "brings back memories."

Romney described the push-button drive gear shift in the car.

"It still worked - 1961 Rambler, pretty impressive," Romney said.

When a reporter asked Romney who Parker thinks will win, Romney posed the question to the little boy.

"Who do you think is going to win Parker, Papa or Barack Obama?" asked Romney, as Parker, appearing shy, pointed at Romney.

"Yeah there ya go, he was taught properly," Romney said.
