OK, the conventional wisdom about the budget President Obama sent to Congress yesterday is that's irrelevant. It's two months late, after all, and the House and Senate have already approved their own spending blueprints for fiscal 2014. But here's why it matters when it comes to health. First of all, the Congressional budget process isn't exactly done. The House and Senate still haven't met to merge their differing proposals (and they are very different) into a consensus plan. So the president's formal input could still mean something, at least in theory.
