The president doesn’t have the authority to just delay the employer mandate part of Obamacare. He can’t just say (as he did) “OK we’ll move it back another year because things are so screwed up.” The law states that it is supposed to go into effect on October 1st 2013.
The GOP in the House offered to make Obama’s decree legal by passing a law delaying the employer mandate. This is what one does in a country which is supposed to be under the rule of law. The president is not king.
But then, fearing an assault on his perceived (by some) power (that whole rule of law thing is such a pain) the President threatened to veto any bill which expressly gave his administration the power to delay the bill.
You see, he has said it will be so, the law be damned. Congress isn’t going to tell him what to do, even if it is the law.
Interestingly a group of Democrats in the house voted to pass the bill anyway. Some even voted to delay the individual mandate as well as the employer mandate.
These Dems knew the president was overstepping his authority and likely because they are vulnerable said something about it. Congress is supposed to write the laws. Congress is a co-equal branch with the Executive ( and also the Supreme Court) of the US government. Obama doesn’t just get to make up the rules as he goes along, no matter how big a disaster Obamcare is.
Also, the main constituency fretting about the delay of Obamacare? You guessed it, the insurance industry. They did write the law so I guess it’s to be expected.
