In 1999, FL "end of life" laws were revised to include "arificial hydration & nutrition" as life support and "persistent vegitative state" as a condition under which life support could be withdrawn. See FL statutes, chapter 765 for details.
George Felos personally lobbied for the revisions. Florida Senate President Jim King drafted the legislation. Jeb Bush signed them into law.
In retrospect, it seems pretty obvious why Felos, a strong euthanasia advocate, was trying so hard to make sure legislation would pass that directly affected the high-profile case which he had just acquired.
Jim King was responsible for restricting the original Terri's Law to one person and later publicly regretted agreeing to that much. He led the Republican opposition to the failed legislation of the past two weeks.
IMO, Jeb Bush unknowingly participated in this set-up. No doubt he'll put the pieces together over time and hopefully get as angry as the rest of us.
