The United States House of Representatives voted today to repeal the ACA. The vote was 245 to 189, with the 245 consisting of 242 Republicans and 3 Democrats. The Senate will not take up the legislation, meaning it has no chance of becoming law.
I will leave it to others, more learned in political science and the political influences on judges, to assess how this might affect the constitutional challenges to the ACA.
(Actually, I lied--I will say one thing. I don't think anyone can say with any degree of certainty how this might affect the litigation.)
