I think it’ll come down to who can sell the pro or con of the legislation better. I think Obama will do better than Mitt because Mitt will come across as unbelievably insincere calling for the legislation’s repeal even as he acknowledges he wants to keep certain popular things such as not allowing insurers to deny based on pre-existing conditions. Plus, there’s the elephant in the room that is Romneycare, people will wonder how Mitt could denounce something so remarkable similar to what he did in Massachusetts. Sure some will buy the 10th amendment bullshit that Mitt and his surrogates have tried but the fact is Obama will have an easier time selling keeping ACA than Mitt will repealing it because ultimately the benefits of the legislation are going to become apparent to the public, the fact that USSC upheld its legality makes the legislation alot harder to attack in the ways that worked in 2010 when constitutionality was uncertain. Not sure, this is all a hunch as the bill remains controversial but make no mistake I think Obama’s road to re-election just got easier.
