I will no longer call it Obamacare or PPACA, because this mess will be around long after Obama is gone, and PPACA is too benign, so I will call it Statist-Care.
Follow the link and read at Cato the manipulations already by the IRS as they try to fix parts of what's wrong with the law -- these tweaks and manipulations will likely go on for a long time as those negatively effected by Statist-Care attempt to dodge the damage.
This government-generated hot mess will create even more uncertainty in the market as the Left demands the law be forced on everyone by any means necessary. The penalties will be stiffer and stiffer, and the enforcement will be stronger and stronger. America is going to get a taste of State power as Statist-Care is gradually implemented. Welcome to a Brave New America.
