The fact is that many Reps, perhaps your Congressman in a "moderate" district, favor mending, not ending Obamacare. It was a useful target to attack politically when they had little power to overturn it. Now that they do, they come up with excuses about a bad bill.
I have read the entire bill. There are lots of good things in it that need to be passed. It is not perfect. Take a look at sections 101 to 251. What's not to like?
It’s not a question of whether there was anything to like in this bill. But even with this bill they estimated that there would be 20% increases in health insurance premiums over the next two years. My representative probably would have lost his seat if that number was 0% and might have been able to keep it if that number was -5%. That’s why nobody wanted to pass this bill. It would have been a political disaster on that basis alone.
