Is Donald Trump just in the race to be president for some fun and publicity this summer? Not according to the Washington Post, which reports that Trump is boosting staff and spending in Iowa, the first state to have a caucus vote in the New Year:

For many Americans, the Trump presidential campaign amounts to a billionaire talking endlessly, and entertainingly, on television. But here in Iowa, it’s another story. Trump is trying to beat the politicians on their turf, building one of the most extensive organizations in the Republican field.

The groundwork laid by Trump’s sizable Iowa staff, with 10 paid operatives and growing, is the clearest sign yet that the unconventional candidate is looking beyond his summer media surge and attempting to win February’s first-in-the-nation caucuses.

The Post reports that even a Trump bus, without The Donald inside, can attract swarms of people as it criss-crosses the state stopping at concerts, festivals and even a WalMart parking lot where about 100 people swarmed the staffer inside the bus:

“I see them as a major threat to all the other campaigns because of the aggressiveness of their ground game,” said Sam Clovis, an Iowa conservative who leads former Texas governor Rick Perry’s campaign.

“You cannot swing a dead cat in Iowa and not hit a Trump person,” Clovis continued. “It’s unlike anything I’ve ever seen. . . . Every event we go to — the Boone County Eisenhower Social, the Black Hawk County Lincoln ­Dinner, the boots-and-barbecue down in Denison — the Trump people are everywhere with literature and T-shirts and signing people up.

Iowa's Republican Governor Terry Branstad says Trump has a real campaign in his state and according to The Post, some old Ron Paul operatives are turning towards Trump.
