Presidential candidate Sen. Bernie Sanders, a self-described socialist, embraces the label. A significant portion of the American public does, too.

Bernie Sanders launched his 2016 campaign this week, and along with it, the resurgence of a certain word in the political lexicon.

And ever since, socialism has remained somewhat of a dirty word in American politics.

“Barack Obama is a socialist,” Sarah Palin said on Fox News.

But there are signs the stigma is wearing thin — among Democrats, anyway.

"Apparently people really want to see a pot-smoking socialist in the White House. … We could get a third Obama term after all,” President Obama said at the The White House Correspondents' Dinner in 2015.

Jokes aside, take the results of this 2014 Reason-Rupe survey. It found 36 percent of the public views socialism favorably — a number that jumped to 50 percent among Democrats and 58 among college-age students.

Sanders' particular brand of socialism he refers to as "democratic socialism." Think less Cuba, more Norway. Here’s how he's explained it.

"Government has got to play a very important role for sure. That as a right of citizenship all of our people have healthcare. That as a right all of our kids regardless of income have quality child care, are able to go to college," Sanders told Democracy Now! in 2006.

In practice, that means regularly voting with the Senate’s Democrats, whom he caucuses with. (Video via Office of Sen. Bernie Sanders)

Though he's further left than his colleagues on a number of issues, including health care. He voted for the Affordable Care Act but said it was "only a modest step forward."

"A Medicare-for-all, single-payer-system bill will eventually prevail," Sanders said on the Senate floor.

Still, the avowed socialist isn’t necessarily the most liberal member of the upper chamber. Wisconsin’s Tammy Baldwin holds that distinction, according to Crowdpac, which analyzes voting records. The Vermont senator came in a close second.
