The Republicans never voted for the ACA, yes that is a fact, but they had a hand in what the ACA looks like.
"Members of the gang, who all sit on the Finance Committee, have negotiated for months to reach a bipartisan agreement, delaying healthcare reform in the Senate beyond a deadline set by President" That's three republicans, none of the three were willing to accept a single payer plan. So what is your explanation of why the ACA looks like  RommyCare?
