It wasn't working-class voters who chose Obama.
Because the alternative was voting for a selfish, thin-skinned, petulant, lying, narcissistic, boastful megalomaniac who committed unthinkable crimes, subverted the republic, committed sedition and treason, ran her own shadow government for personal gain, sold her office as SOS for hundreds of millions through phony "charities," enabled her serial rapist husband to avoid prosecution, and is the whiniest bitch sore loser America has ever known. That's why.
Reich could have been talking about the 1992 election as well.
“Why did working-class voters choose a selfish, thin-skinned, petulant, lying, narcissistic, boastful megalomaniac for president?”
They didn’t, Clinton lost.
