As the Obamacare law is written, the employer mandate is to begin in January 2014. This is what the law said when it was passed by the House and Senate, and signed by President Obama in 2010.
However, it has been reported that President Obama has just delayed the employer mandate part of Obamacare until January 2015. Obama did this without approval from Congress.
For Obama to change a law that was passed by Congress, without first getting approval from Congress, is a violation of the Presidential oath that Obama took to uphold and defend the Constitution.
What Obama did here is an action of a dictator, not an action of a President whose power is limited by a written constitution.
If Obama can get away with this, then it sets a horribly dangerous precedent, and means that the President can arbitrarily make any change to any law that has been passed by Congress, without first getting approval from Congress. About these ads
