I’ve been surprised about the unhinged rhetoric being directed at the Republican tax cut bill passed by the Senate last Friday.

Some of it is standard partisan stuff. “This is class warfare,” says Sen. Bernie Sanders, the No. 2 finisher in the 2016 Democratic presidential primaries, according to the Washington Post. “The wealthy and big corporations are getting most of the benefits,” says ace Democratic electoral strategist Guy Cecil. Of course, as I pointed out in my Washington Examiner column last week, when you start off with a progressive federal income tax system, any rate cut will tend to provide most of the dollar benefits to high earners, who by definition provide most of the revenues. And when you cut the corporate tax, which Democrats from Barack Obama on down have been saying should be cut since at least 2012 (because it’s just about the highest in the world), then corporations will be paying less.
