When 10 million people sign up, republicans will rush to yell
"See I told you Obama was lying about 7 million insurance signups! It's 10 million.
Obama is the worst liar in history!!!"
By the way, when an insurance company dropped you after you got sick before the ACA, you couldn't keep it your insurance then either. So Obama never should have made that promise, as it was obviously contrary to reality, both before and after the ACA.
The main difference is that now you are guaranteed the ability to purchase real health insurance. It's a tragedy I know...
