At some point, you really can't blame Republicans for hating Obamacare. And, not even because of the law itself. After all, they were lied to and cheated in order to get it passed.
They were promised a seat at the table to negotiate. There was 1 meeting the WH where they were invited.
Obama said he'd meet with every member of Congress to discuss. I personally know at least 2 who never had such meeting (and most Reps said they never got it).
We were promised that all debates would be televised via CSPAN. They weren't.
It was passed at the last minute, in the middle of the night, without giving anyone enough time to read the final version.
Again, I don't want it repealed (changed slightly, not repealed). But, I can sympathize with the members of Congress who were there when it was passed.
