AMBERSON, Pa. — “IMPEACHMENT NOW MAKE AMERICA GREAT AGAIN 2018” blares the all-capital letters on a massive billboard along the Pennsylvania Turnpike.

It’s a surprising contrast to the thousands of homemade “Make America Great Again” signs that were scattered across towns, suburbs, farms and cities in this state, all supporting candidate Donald Trump ahead of the 2016 presidential election.

The billboard is clearly the work of a professional. His name is Claude Taylor, and he says on his website that he is a “veteran of three presidential campaigns that served on White House staff for Bill Clinton.”

Even so, if you were traveling on the fast-moving turnpike and spotted Taylor’s sign, you might think something was amiss in Trump Country. In fact, you might believe that by now, given all the news surrounding Russia, Trump’s tweets, his alleged dalliance with porn star Stormy Daniels and the raids on his lawyer Michael Cohen, his supporters would have fled the coop.

You would be wrong.

In the past three weeks, I have traveled to Chicopee, Mass., Raleigh, NC, Harrisburg, Pa., and hundreds of towns in between. Among those three cities, none of them voted for Trump. Hillary Clinton won Chicopee by 10 percentage points and doubled that in Raleigh, while Harrisburg is always solidly blue.

So you’d think the people who voted for Trump in these towns would be the first to give up on the president because family or friends or colleagues pressured them to do so.

But, in fact, their support has only hardened.

“I was a skeptic on election night,” said Daniel, a businessman in the banking industry in Harrisburg, who asked me not to publish his last name. “I honestly was unsure of who I would vote for that night, but I decided against what some said was my better judgement to vote for Trump.” (No one I talked to wanted their full name printed out of fear of blowback.)

He added with a broad smile: “Turns out to be the best vote I’ve cast since Reagan.”

On Stormy Daniels, he shares the same opinion as many of his supporters. “I knew who this cat was going in, known who he was for 20 years,” he said. “Had he tried to position himself as the paragon of virtue beforehand, he would have been like every politician, but I made my peace with his character. What I was hoping for was results, which I have gotten in spades,” he said.

Daniel is happiest about tax reform, is thrilled with Trump’s judicial picks and sanguine about his dealings with the media and culture.

“For forever, if you had the wrong ZIP code, your viewpoints were held in contempt by the news media,” he explained. “I get it, I went to an Ivy, I lived in New York. But never did I once believe that viewpoints there were more important than viewpoints in any other part of the country. But you know what? A lot of people do, and you hear it in the inflections of the reporters and the anchors.”

“No one’s had our back,” he said. “He does.”

David, a tall, slim businessman from just outside Harrisburg, is also ecstatic when it comes to tax cuts. “I am certainly no millionaire,” said David, who runs a family-owned equipment company. “So it just burned me to hear this tax cut is for millionaires. Most of the money I make from my manufacturing plant, I put right back into my business. This ultimately helped my employees because I can now move more stock, which means they got a bonus. That, in turn, helps my community because the money goes back in the small businesses where they live.”

In Raleigh, an academic shuddered at the idea that she’d tell anyone she voted for Trump. “You just keep that to yourself,” she said.

On Stormy Daniels, she shrugged. “Honey, Bill Clinton let that cat out of the bag 20 years ago when he was president.”

She is most impressed with Trump’s judicial picks. “We need more center to center-right temperament on the court. On this alone I would vote for him again.”

In Chicopee, it was surprisingly easy to find Trump supporters — from small-business owners to public-service staffers to waitresses — and they were all unflinching in their support.

No fancy corporate billboards are going to change anyone’s mind

For these people, America in 2018 is an odd world to straddle. They hear pundits discuss Trump supporters, and they know that “Make America Great Again” is considered a dog whistle to fascism. They know Trump’s message is seen as angry, racist, scary, dangerous and backward-looking.

But to these voters, it’s aspirational and forward-marching — something bigger than themselves. According to a Quinnipiac poll last week, 58 percent of white voters without a college degree approve of Trump’s job as president. And 44 percent of these same voters approve of him strongly.

Yes, of course, a small percentage harbor darker feelings. But every Trump supporter I interviewed wants that element to take a hike.

It is no different from radicals on the left who express anti-Semitic views but support Democratic candidates. Most decent Democrats want nothing to do with them.

The honest truth is it is still Nov. 8, 2016, in this country. If you voted for Trump you are, for the most part, optimistic about what he can do in the future. And if you didn’t vote for him, you still believe he is not worthy of the presidency. No fancy corporate billboards are going to change anyone’s mind.

Where his supporters go next is anyone’s guess, but because they are a force to be reckoned with in modern politics, shouldn’t we stop treating them like anthropological studies and start listening to what they have to say?
