Republicans debating what they should stand for often invoke Ronald Reagan as the ideal standard-bearer for the party. It’s a shame, then, that so many of them misunderstand the man. Reagan’s legacy is often articulated as a simple, policy-focused creed. Former Wisconsin governor Scott Walker immediately summarized that creed during a recent interview: “limited government, low taxes, strong national defense.” But Walker — who now heads the Young America’s Foundation, which owns the Reagan Ranch and the president’s boyhood home — also noted that these are timeless principles rather than ironclad prescriptions.
