FOUNTAIN VALLEY, Calif. — In many ways, Dr. Mai-Khanh Tran isn’t all that different from millions of other Democrats who have been dismayed or depressed or indignant since Donald Trump was elected president.

On election night, Tran watched in shock as the returns rolled in. The next morning, she wept at work — Tran is a pediatrician — with her colleagues. Later, she joined the protesters shouting slogans and waving signs outside the Orange County offices of several Republican congressmen.

But Tran didn’t stop there. Last month, she actually decided to enter elected politics herself, launching a long-shot campaign to unseat 12-term Republican Rep. Ed Royce, chairman of the House Foreign Affairs Committee.

While defeating Royce may seem like a tall order for a political novice, Tran, 51, has already spent her entire life overcoming impossible odds.

In 1975, Tran arrived in America as a 9-year-old refugee from war-torn Vietnam — without her parents. She spent her summers picking strawberries in rural Oregon, eventually working her way through college at Harvard as a janitor. And she survived two bouts of breast cancer and endured eight rounds of in vitro fertilization before finally getting pregnant at age 46.

“I think you’ve got to have total commitment to everything you do in life,” Tran said on a recent Thursday afternoon as she sipped from a bowl of bone-in kalbi soup on the patio of a new pan-Asian restaurant in Orange County’s Little Saigon. “You’ve got to do things for the right reasons. And when you have the right reasons — if what you’re doing is needed, on behalf of others — you will do it until you succeed. I truly believe that.”

Whether Tran can succeed her in mission to topple Royce remains to be seen. But if any place encapsulates the challenges facing Republicans in 2018, Orange County is it. And if any Democratic hopeful embodies the political crosscurrents that will likely define the coming midterms, Tran may be the one.

Topping the list of those forces? Health care.

The first patient Tran saw the morning after the election was a child with a brain tumor. The girl’s mother, a local nail salon worker, couldn’t get health insurance for her children until Congress passed the Affordable Care Act in 2010. Realizing that her coverage might change under Republican rule — that “this was going to affect her daughter’s life soon” — the two women cried together in Tran’s examination room.

A few months later, the mother called Tran. The House had just passed the American Health Care Act — the GOP’s Obamacare repeal bill — and she was, according to Tran, “petrified.”

That’s when Tran decided to run for Congress.

“It was the speed of that vote, the secret way it was done, that just pushed me,” Tran told Yahoo News, noting that she had spent the previous three months appearing on local Vietnamese-language TV to explain what was at stake. “I thought, ‘We can do all the prep work, all the work to inform the public, but when it comes down to it, their voice just isn’t there where it matters. On the floor. In the caucuses. All of the meetings.’ It just made me so angry. And I said, ‘You know what? We need to have people who really understand health care in Washington. We need to be in the game.’”

As the Republican Senate struggles to pass its own version of a bill to repeal Obamacare, health care is shaping up to be the central issue in 2018.

In part, that’s because 217 GOP House members — including all four Orange County Republicans — voted for the AHCA, a deeply unpopular measure that even President Trump has called “mean.” Democrats plan to spend millions of dollars between now and next November reminding voters of this fact.

The so-called resistance to Trump — and, more specifically, the resistance to his party’s Obamacare repeal push — has inspired newcomers like Tran, many of whom are also doctors or scientists or women, to get off the sidelines and run for office themselves.
