It turns out that about 6 million people have signed up for lower-cost health insurance under either the health care exchanges or are eligible for the Medicaid expansion under the Affordable Care Act, the latter being designed to take care of those who earned too little to be eligible for the former. That is undoubtedly good news.
But what the designers of the ACA did not anticipate was the sheer cussedness of Republicans who, in the states controlled by them, decided not to allow the Medicaid expansion even thought the federal government pays 100% of the cost through 2016 and 90% in the subsequent years. As a result, an estimated 5 million such people in 25 states do not have insurance.
The sheer callousness of this action, inspired almost entirely by spite against the ACA, boggles the mind.
