William Saletan notes that while many polls say Bernie Sanders would fare better than Hillary Clinton against Donald Trump or Ted Cruz, that's the Unattacked Bernie Sanders — the one Republicans haven't even tried yet depicting as a dangerous commie socialist who'd raise your taxes, redistribute wealth, put the government in charge of your health care, weaken the military, etc. Even though I'm voting for Sanders, I can't deny that his popularity would take a sharp hit if he were the nominee and the folks who brought you the Willie Horton ads and the Swift Boat Veterans went to work on him.
