Trump appears to be borrowing some of the language behind a traditional conservative Republican health reform proposal, which involves facilitating competition in health coverage through the sale and purchase of insurance products across states. It’s sometimes referred to as interstate competition or competitive federalism, or even just “consumer choice.” The origins of this proposal have a history of almost 15 years. Some business groups in the small-group market started floating the outlines of this idea in 2001. I wrote the first draft in policy terms at a Cato conference in July 2001, and subsequently published the academic-style version in the Cato Journal the following year. Then-Rep. Ernie Fletcher (R-KY) proposed the first legislative bill on this front in 2002. Subsequent tweaks to those concepts on Capitol Hill were championed by then-Rep. John Shadegg (R-AZ), and, in later years, by Rep. Tom Price (R-GA) and Rep. Marsha Blackburn (R-TN). Presidential candidate Ted Cruz introduced a bill similar to Blackburn’s in the U.S. Senate.
