Back during the primaries there was another poster, like the OP, from the right who also had problems realizing why one can vote for Clinton:

We might then ask, what stances will be the centerpiece of her campaign? What does she care about deeply? What is she willing to fight for, even when it means taking risks? No answers seem forthcoming. If she has a firm commitment to stopping global warming, ending police brutality, balancing the budget, defending civil rights, or doing anything else, she’s not made it clear in either her past actions or her present words.
As I replied then:

Across the ideological divide, however, one prospective presidential candidate, Hillary Clinton, was busy embracing the law, as well as the man who’s name is so closely associated with it.
Clinton, who had tried and failed to push through a single payer healthcare system as First Lady, has defended the Affordable Care Act before, even while acknowledging some of its faults.

“The science of climate change is unforgiving, no matter what the deniers may say, sea levels are rising, ice caps are melting, storms, droughts and wildfires are wreaking havoc,” Clinton said, according to ABC News.
“The political challenges are also unforgiving, there is no getting around the fact the kind of ambitious response required to effectively combat climate change is going to be a tough sell at home and around the world at a time when so many countries including our own are grappling with slow growth and stretched budgets.”
But acknowledging the political challenges did not stop Clinton from calling for action. “If we act decisively now we can still head off the most catastrophic consequences,” she said.
She expressed hope in technological advancements’ ability to make progress on the issue, calling to “dare greatly and lead boldly” in order to “protect our heritage and preserve our future.”
During her speech, she declared, “yes, black lives matter,” a mantra of demonstrators around the country who have been protesting recent grand jury decisions not to indict white police officers involved in the deaths of unarmed black men in Ferguson, Missouri, and in New York.
Clinton, a former U.S. first lady, New York senator and U.S. secretary of state, is viewed as the likely Democratic presidential nominee if she runs. She was honored at the Kennedy organization’s star-studded Ripple of Hope Award ceremony.
I said then that based on that, I have to say she will get my vote. And even more nowadays as Trump is just bigotry and ignorance of science personified.
