As Gabriel Malor at Hot Air notes, Trump’s plan boils down to expanding Medicaid:
According to Trump, uninsured people are going to get coverage because he’s going to “make a deal with existing hospitals” and “the government’s gonna pay for it.” There’s a word for this exact proposal: Medicaid. Trump probably doesn’t know this, but Medicaid expansion was a huge part of Obamacare. The “deal with existing hospitals” is so unfavorable for doctors and hospitals that many of them do not accept Medicaid patients because it would put them out of business. Does Trump know this? Meh, he doesn’t care.
It will be interesting to see if Trump’s supporters, most of whom presumably opposed Romney because of RomneyCare and Obama because of ObamaCare, will jump on the TrumpCare train.
