Khanna: Here’s what I don’t understand. I’m for taxing the billionaires more. In the 435 districts in America, no one has more billionaires than my district. If the guy who has all the billionaires can say, “Tax them more,” how is this a hard vote for the other 434 members? We need to tax the billionaires and the ultra-wealthy to provide Medicare for All, universal education, and fairness in America.
