Senator Elizabeth Warren is famous for hurling at least one major plan against every policy issue and societal problem you ever heard of—or hadn’t. It’s true that a lot of them make my head ache, some of them turn my stomach, and practically none seem likely to get enacted during her lifetime, even were she to win the Oval Office. Still, her plans often contain provocative ideas, not all of them bad. At least she’s thinking about big, substantive matters and going after them with big, substantive proposals. That’s a nontrivial part of what a presidential candidate—or president—should do.
