Rep. Alexandria Ocasio-Cortez (D-N.Y.) has called for a dramatic increase in taxes paid by really, really wealthy people. Republican leaders in government and the punditry have reacted like she's proposing that we dismantle the United States of America and turn the whole thing into a chain of Chipotle restaurants. But at least according to one poll, that idea fares well with Democratic voters and Independents, and doesn't even do so bad with Republicans.
