When Congress decides how to pay for President Obama's healthcare initiative, some of his strongest political bastions may be footing a heavy bill. Some of the "bluest" states that propelled Obama into the White House are among those most likely to pay more in taxes to fund expanded health insurance coverage and make other changes to the system, analysts say. People in states such as Illinois, New Hampshire, Massachusetts, Connecticut, and New York have a higher share of wealthier taxpayers and residents who get generous healthcare plans through work—and both sets of people may be tapped to raise money for the healthcare overhaul.
