When you have the Senate of the United States wasting time passing resolutions on things that no one has campaign on, like the Washington Redskins needing to change their name, without many liberals having a coniption fit about time being wasted then I think it's not unreasonable to spend the little time that it'll take to pass a repeal bill using reconcilliation and to get it vetoed.
If you foolishly think that politicians aren't going to play politics that's on you. Imagining that will be the case isn't being an "adult", it's more akin to being a child filled with imagination and naivity. Yes, both sides are still going to act like politicians after this election, both sides are still likely to take action that's going to be aimed at pleasing the people who voted them into office, and both sides are going to try and manuever a bit to prepare for 2016.
If they spend 6 months battling for full repeal, instead of taking a bit of time to do that and immedietley moving on, then I think you'd have a point. I don't see that likely being the case, and until it proves to be the case I'll base my thoughts on the more likely occurence...that they try in relatively short order, they fail, and they move on to the other means. I don't see anything significantly wrong with that, in part because I do believe that those elected into office have a duty to actually stand up and try to do what they campaigned for.
