What did you think of the bunch of socialists you just saw debating on stage?

Wait, you may protest, you didn’t see any socialists up there. And you’d be right. The Democratic Party has clearly moved left in recent years, but none of the presidential candidates are anything close to being actual socialists — no, not even Bernie Sanders, whose embrace of the label is really more about branding (“I’m anti-establishment!”) than substance.

Nobody in these debates wants government ownership of the means of production, which is what socialism used to mean. Most of the candidates are, instead, what Europeans would call “social democrats”: advocates of a private-sector-driven economy, but with a stronger social safety net, enhanced bargaining power for workers and tighter regulation of corporate malfeasance. They want America to be more like Denmark, not more like Venezuela.

Leading Republicans, however, routinely describe Democrats, even those on the right of their party, as socialists. Indeed, all indications are that denunciations of Democrats’ “socialist” agenda will be front and center in the general election campaign. And everyone in the news media accepts this as the normal state of affairs.

Which goes to show the extent to which Republican extremism has been accepted simply as a fact of life, barely worth mentioning.
