Medicaid as a share of state spending has grown faster in Maine than anywhere else — but that may be on its way to changing.

Maine tops a list released Wednesday by Pew Charitable Trusts ranking states by growth in the share of their total revenue devoted to the low-income health insurance program. Every state but North Dakota is spending more cents out of every dollar on Medicaid than in 2000, the report shows. The data stops short of 2014, before the expansion of Medicaid through President Obama’s healthcare law.
