Well, for starters Karin, it's going to take a 2/3 majority in both houses to repeal any of it as long as O is Prez, and by the time he's out, benefits will have started.
Some parts of it take effect at once though, I foresee group insurance rates rising significantly as a bunch of 23-26 year old adult children are suddenly added to policies, although it's generally a low-claim group, it does include a lot of young women bearing children as well as just a bunch of additional dependents generally. The Forces of Darkness will claim that the necessary increase in rates is 'Exploitation' (Some of which will no doubt also occur) by the eeeevil insurance companies.
