There is proof out there...the history is there...
Tennessee launched TennCare in 1994 to cover the uninsured. Started with a budget of $2.6 billion, it quickly took up one-third of Tennessee's budget as costs grew to $8.5 billion in 2004.
The state stopped the program in 2005, cutting 170,000 from the plan. It now offers "Cover TN" that limits annual coverage to $25,000 in medical costs at significantly higher premiums and co-pays; the program is still in deep financial trouble.
Maine implemented its plan, including a public option ("DirigoCare") in 2003. Touted as "self funded" (no new taxes), the program has added $155 million to the state budget, requiring increased taxes on beer, wine, soda and paid health insurance claims and has increased health premiums substantially. The state now does not allow new entrants.
Massachusetts started its plan in 2006 with an initial annual budget of $450 million, which it overran in six months, spending more than $650 million that year and requiring federal subsidies annually since. The state subsidized more than 200,000 uninsured, which has resulted in emergency room visits exploding.
Since 2005 insurance costs have risen 21 percent to 46 percent faster than the rest of the nation and employer-provided premiums are now the highest in the nation.
Massachusetts is so pleased with its medical care voters elected a Republican to the Senate in anger over their experiences.
