Phil Galewitz and Matthew Fleming surveyed all 50 states to find out how Medicaid budgets are changing. They found that 13 states had made cuts this year. I put them onto this map, color-coded by the party affiliation of the state's governors:

It's hard to find any common thread among these 13 states. Seven have Democratic governors; six are led by Republicans. Three are in the south and an equal number are in New England. Two, California and Connecticut, seem to really like the Medicaid program: They volunteered to start the health law's Medicaid expansion early, well before it's required in 2014. Others, like Louisiana and Florida, are not fans at all: They plan to sit out that Obamacare provision.

All told, it's pretty hard to find any narrative that explains why these states have cut their Medicaid programs, aside from some broad truths: Budgets are still squeezed and Medicaid is eating up a growing chunk of state spending.
