Three states—California, New York and Massachusetts—are receiving 37 percent of all Obamacare funds, according to a group of Republican senators. As an example of this inequity, Pennsylvania has nearly twice the population of Massachusetts, but it receives less than half as much Obamacare money.

The senators propose to radically change that distribution by giving each state Obamacare funds in the form of a block grant. Eventually, each state’s share of the total would equal its share of the country’s poor and near-poor population. That means the people who are the principal target of Obamacare funding will have access to the same federal resources—regardless of where they live.
