Under Florida Gov. Charlie Crist's "Cover Florida" proposal, the estimated 3.8 million Floridians who lack health insurance would be offered an affordable plan for "$150 a month or less." The proposal would not come with a state mandate that individuals had to buy it or employers had to offer it. Cover Florida also would give insurance companies lots of leeway in deciding how to structure such a health plan. Experts say the plan is doable, but people would need to rein in their expectations when it comes to coverage for hospital stays and other high-ticket medical costs.
