President Obama will travel today to Massachusetts, one of only two states to implement a universal healthcare program similar to his ambitions for the entire country. But he does not plan to use the trip to make his case for far-reaching reform; he will tout clean energy and raise money for the Democratic governor. The president's critics say his reluctance to spotlight the Massachusetts model is real-world evidence that his vision would not work on a national scale. High costs have forced the state to trim benefits for legal immigrants and prompted one safety-net hospital to sue over a $38 million shortfall.
