That one doesnt sound that hard to change back without causing a fuss, assuming Romney disagrees with it.
I do remember in 2010 and 2011 you warning that if any version of O-care passes it will be VERY hard to get any of the free-bees repealed for the same reason you cite above.
Note the problems Romney is having regarding his repeal promises and the pre-existing data mandate. He was quized on this earlier this year and said he wanted to out-law pre-existing conditions exclusion's as long as the person is covered by insurance by say another insurer, Obviously this gets complicated if you try to really come up with a law.
At the DNC they dragged up Moms on stage who claiming that this regulation saved their kids lives (kids pictures shown) and they would die if Romney repeals it.
Reality is Republicans in congress probably couldnt get a full repeal bill to Romney's desk.
Correction :2009 and 2010 , 2011 Rs had the House
We'll see what happens if R gets elected. Who knows, maybe he will have a Reagan epiphany. All I am saying is, don't be too disappointed if he doesn't turn out to be as anti-obama as expected. We know he has a dubious record.
