Depends on whether you're willing to call a wolf-dog a wolf.
East Coast coyotes are apparently full of dog DNA, as well as wolf DNA. So maybe they bark, or even howl a bit. But I maintain that barking remains a dog thing.
Leftists won the last three big wars, so even most of today's "conservatives" are more than a little hybridized. You won't find any independent clade of wolves who bark for their own separate wolf reasons. Barking is a marker of dogness, egalitarianism is a marker of leftness.
