Mandating people to buy coverage can not be found in the constitution! 

ACA was an act shrouded in secrecacy and had to be passed to know what was in it. No Republican thought it a good idea to pass a law without knowing what was in it. However this strategy represents the Democrat ideology. 

Do it in secret, say it is good, say it will reduce costs, say you can keep you coverage, say you can keep your doctor. Say all good things because they do not have to be true since the main stream media will not really cover it.  Next gloss over the IRS roll in penalizing citizens both civilly and criminally for not complying with the mandate. 

Most folks feel this was a betrayal by their representatives. Some think it was a brilliant strategy.
