Louis C.K. is known for using his edgy humor to confront serious issues like racial injustice and sexual assault. So it's no surprise that he took on Donald Trump in an email to fans March 5. What's surprising is that he isn't treating The Donald as a laughing matter.

"Please stop it with voting for Trump," he wrote. "It was funny for a little while. But the guy is Hitler. And by that I mean that we are being Germany in the 30s. Do you think they saw [this] coming? Hitler was just some hilarious and refreshing dude with a weird comb over who would say anything at all."

Then he pleaded with fans to vote for anyone other than the billionaire businessman:

"Please pick someone else. Like John Kasich. I mean that guy seems okay. I don't like any of them [Republican candidates] myself but if you're that kind of voter please go for a guy like that. It feels like between him and either Democrat we'd have a decent choice. It feels like a healthier choice. We shouldn't have to vote for someone because they're not a shocking [billionaire liar]."

That's not exactly a ringing endorsement for Hillary Clinton or Bernie Sanders. But other comedians are just as passionately opposed to Trump as they are in favor of Bernie Sanders and his plans to repeal federal marijuana prohibition. Here are four examples:

Bill Maher

In February, the irreverent political commentator Bill Maher stopped by Jimmy Kimmel Live and explained why he supports the Vermont senator: "He's saying we could be more like a European democracy where you pay a little more taxes, but look what you get – free college, free health care, go after the banks. This stuff has never been on the table."

Here's Maher translating one of Hitler's speeches into Trump-isms on Real Time:

Sarah Silverman

At a rally in October 2015, the flippant comic praised Sanders for his values, his record on social justice and his views on R and B:

"His moral compass and sense of values inspires me. He always seems to be on the right side of history....Not only was he fighting for civil rights in the 60s. He was fighting for gay marriage in the 80s. He was against the Iraq War, against deregulation of Wall Street that led to the 2008 collapse, and, most importantly, against the breakup of Destiny's Child."

Check out Silverman, Patrick Stewart, Bryan Cranston and others struggling to describe the color of Donald Trump's hair:

Margaret Cho

The multitalented comedian and star of the upcoming marijuana dramedy Highland is hoping for a Sanders-Clinton ticket in 2016.

"I am a longtime fan and friend of Hillary Clinton, but I have decided to endorse Bernie Sanders - I #feelthebern. It would be great if they could run together, that is my hope."

And she's also hoping to see less of The Donald and more Asian American talent featured on shows like Saturday Night Live:

Tommy Chong

It's no surprise that the longtime marijuana advocate and cannabis culture icon has endorsed the presidential candidate who is the most liberal on the cannabis issue. In January, he released an endorsement video telling voters, "I know this year you and I are going to Feel the Bern. There's one candidate that stands head and shoulder above them all, who's weathered all storms…Bernie supports the legalization that I care about – legalization of the super medicine, marijuana."

Here's Chong slamming Trump as a caricature of the Republican party:
