At present, 24 States (and DC) have decided to move ahead with the Medicaid expansion provided for in Obamacare, and 21 have rejected expansion, while 6 are still considering their options. If the current decisions hold, it will result in a self-imposed redistribution of money from poorer (and typically Red states), to richer (and typically Blue ones).
According to an analysis I have done using Kaiser Family Foundation data–in 2016 alone–the 24 expanding states will receive $30.3 Billion additional federal dollars, while those not expanding will forego an additional $35.0 Billion they could have had (the fence sitters have an aggregate $15.2 Billion at stake in 2016). This represents a huge redistribution of federal money from non-expanding to expanding states.
He then lists some of the states–for example Florida is losing $6.7 billion while California is gaining $7 billion, in effect Florida is sending all its Medicaid money to California (of course, states such as California are net payers to the federal government, but ignore that for now).
