People that criticize Romney, why does Mass. have a 95% insured rate in Romneycare is failing?

As a liberal, I'm no supporter of Romney at all. but the facts are facts, you can not just deny facts just because you don't like them. Romney's healthcare plan has made it so that 95% of his state is covered. And what baffles me the most, is that Republicans don't like that fact like it is a bad thing?!?!
