Republicans are gearing up to replace President Barack Obama's healthcare plan, designed to cover 30 million people who don't have insurance. Just don't expect a package that goes nearly as far to cover the uninsured. The GOP's main goal is cutting costs for people who already have health coverage — not creating a vast government bureaucracy to cover people who don't. The differences could be stark. The closest model to what Republicans are suggesting now — a substitute plan they offered in the House in November 2009 — would have covered just 3 million of the uninsured. In fact, there is no House Republican plan yet, but the broad outlines of a GOP plan are becoming visible.
