While announcing the sixth episode of his web series, Horace and Pete, Louis C.K. adding a long P.S.

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

The actor and comedian went on to say he likes both Bernie Sanders and Hillary Clinton, although he’s not soliciting votes for either.

“And I’m not advocating for Hillary or Bernie. I like them both but frankly I wish the next president was a conservative only because we had Obama for eight years and we need balance. And not because I particularly enjoy the conservative agenda,” he continues. “I just think the government should reflect the people,” adding, “A good smart conservative to face the liberal candidate so they can have a good argument and the country can decide which way to go this time.”

Louis C.K. went on, critiquing Donald Trump.

“Trump is not your best. He’s the worst of all of us,” he tells conservative voters, while also assuring them that he’s “not saying vote democrat.”

“He’s a symptom to a problem that is very real,” he writes. “But don’t vote for your own cancer. You’re better than that.”

What’s your take on Louis C.K.’s warning about Donald Trump? It’s kind of scary when comedians get serious about what’s happening in the political arena–don’t you think?
