President Obama is proposing to boost federal funding for states that choose to expand Medicaid under ObamaCare in a new effort to entice states to make the move.

Obama will propose in his 2017 budget to have the federal government pick up the entire cost of expansion for three years, no matter when a state decides to accept the expansion.

Under current law, states only got three years of full federal funding if they accepted the expansion in 2014. If nothing changes, states newly accepting the expansion would not get full federal funding after 2016 and instead would get payments that are somewhat less, eventually dialing back to 90% of costs.
