"Contrary to the suspicions of some people on the right, Collins isn’t a closet Democrat. She voted to confirm Neil Gorsuch to the Supreme Court, and for all but two of Donald Trump’s Cabinet nominees. In 2010, she voted against the A.C.A.; in 2011 and 2015, she voted to repeal it. On many occasions, she has criticized the 2010 reform for offering Americans limited choices and high premiums and deductibles. But, unlike most of her G.O.P. colleagues, Collins has also defied the Party line and recognized some of the good that Obamacare has done."
