Hillary Clinton seems to have screwed up this email thing, both by violating some federal archiving rules and then subsequently by botching her initial public explanation of why she didn't. Bad on her.

At the same time, this week saw the release of a new Republican tax plan from Republican Senators Mike Lee and Marco Rubio that's notable for embracing large tax cuts for rich people. That's nothing new for Republicans, of course, but it's noteworthy because last year Lee was pushing his colleagues to move away from tax cuts for the wealthy as the centerpiece of conservative economics.

Of the two stories, Clinton's emails have received by far the most attention. But it's the Rubio-Lee tax plan that actually matters most for the presidential race — and for people's lives.

The Clinton email story has been catnip for political reporters because it doesn't involve difficult-to-master and controversial-to-answer-policy questions. Instead, it offers ample opportunity to engage in ideologically neutral speculation about Clinton's competence as a campaigner. But political stories are interesting only because policy stories are important. The dynastic struggle between the Clinton and Bush families is profoundly boring compared with the dynastic struggle on Game of Thrones. It's only interesting because the real-world stakes are high. And the real-world stakes are high because of things like the Rubio-Lee tax plan.
