Two things:

The subsidized insurance program at the heart of the state's (MA) healthcare initiative is expected to roughly double in size and expense over the next three years - an unexpected level of growth that could cost state taxpayers hundreds of millions of dollars or force the state to scale back its ambitions...

State projections obtained by the Globe show the program reaching 342,000 people and $1.35 billion in annual expenses by June 2011...

The state has asked the federal government to shoulder roughly half of the program's cost from 2009 through 2011...*

If you think any form of mandated healthcare will not result in a massive swelling of ranks at the Federal trough, think again.

In the absence of reform, lawmakers would eventually have to choose between permanently raising taxes by a staggering 10.3 percent of GDP (the equivalent to $11,000 per household today) or eliminating every other federal program in order to fund Social Security, Medicare, and Medicaid.**

Not only is there no cash for a military (which may get applause from some riders) there is no cash for education, transportation, law enforcement... you get the idea.
