The Onion has always been very political with a liberal slant. I have some of their print collections from the early 2000s and they're similar to today's Onion with maybe a little more edge.

Their gun control headline "'No Way to Prevent This,' Says Only Nation Where This Regularly Happens" (https://en.wikipedia.org/wiki/'No_Way_to_Prevent_This%2C'_Sa...) dates to 2014.
