Cory Booker is unveiling a bill to make the first $75,000 of income tax-free, and is clearly warming up a 2028 presidential pitch while doing it. "Americans are working harder and harder, and they're making less and less relative to their parents and grandparents...So we need big ideas that could redeem the dream of America." It's a genuinely big idea. Whether a Democratic Party that spent the last decade allergic to economic populism has the stomach to actually run on it is a different question entirely.
