It's just before rush hour, and there's a line snaking around the massive Farm Show Complex & Expo Center in Harrisburg.

The hundreds of Donald Trump supporters, who were already in line by 3:30 p.m. Thursday, don't seem to mind the occasional raindrops.

They're donning shirts bearing his likeness - some with messages more graphic than others - and cheering the billionaire's last name.

"Trump! Trump! Trump!"

Sometimes they change their chants to a patriotic "U.S.A.!" as cars passing by honk their horns in an afternoon caravan.

Many of them are here to see Trump speak in the Large Arena, with its dirt floor and stadium seating, for two reasons: They think an executive should be in charge of the country's executive branch, and they believe Democratic frontrunner Hillary Clinton belongs in jail.

In fact, some of their shirts say "Hillary in Jail 2016."

But, despite the "Anyone But Trump" movement against the TV personality and hotel magnate, this is not an "Anyone But Hillary" crowd.

These people want Trump. Not Ted Cruz. Not John Kasich. Not a contested convention with House Speaker Paul Ryan or former GOP candidate Mitt Romney.

They want Trump.

They especially want his steadfast and relentless approach to immigration, with many in the crowd saying the U.S. can't afford anymore "illegals."

"Build the wall," Diane Cwanek said with gusto.

The Lebanon County grandmother said she couldn't pass up an opportunity to see in person the businessman she's admired since the 1980s.

"He's the only candidate who can really turn the country around," she said.

Many others in line are wearing the trademark red hats and believe in the "Make America Great Again" message stretched across the front.

"I believe it needs to happen, and I believe he can do it," said Halifax resident Bob Frongillo.

As supporters prepared to wait at least three hours for the 7 p.m. Trump campaign speech, bomb-sniffing dogs and Secret Service searched bags and secured the Farm Show complex.

A half hour later, voters were taking their seats in the Large Arena while Capitol Police moved through the growing crowd.

"This is exciting," said Hershey resident Paul Flannery. "Bring on Trump."
