Why did Hillary Clinton campaign Wednesday at Adams City High School in Commerce City, Colo.? That's a great question.

According to Nicholas Garcia at Chalkbeat, it's one of the worst schools in the state. None of the students there scored well enough on the state's English test to be deemed "college-ready." Because of a low graduation rate and average ACT score, the state has considered the school "low-performing" for six years.

But the school doesn't just suffer from academic problems. It has racism and abuse problems too.

"In 2010, a teacher at the high school kicked a group of Hispanic students out of class because the students were speaking in Spanish," Garcia writes. "A riot in the class nearly followed."

In 2014, the U.S. Department of Education's Office of Civil Rights determined the school district was a "hostile environment" for Latino students and teachers. Now administrators and teachers have to undergo frequent training on racial issues.

Clinton's speech focused on the economy, not on education, which could explain why the venue wasn't important to the substance of the speech. The school is also in a neighborhood with many Latino and working-class voters. But still, with such a dubious past, why would anyone take their chances and campaign there?

Oddly enough, Clinton isn't the first Democrat to campaign there. There's been a major visitor every election year since 2004. John Edwards visited the school as the vice presidential nominee in 2004. Joe Biden did the same in 2008. Then in 2012, President Bill Clinton campaigned for President Obama's re-election there.

"It's unclear why the high school has become a favorite stop for Democrats," Garcia writes. Unclear, indeed.
