To tie my point about Obamacare back to the thread, we need to keep in mind that just because an action at the state level is bipartisan, it doesn't mean that Congress will treat it as such. Congress has its own dynamics independent of the states. Obamacare may have been derived from Romneycare, but bipartisan groups in Congress had been working in other directions prior to the 2008 election. Any MA bipartisanship on that issue was not going to translate to DC. Similarly in 2014 MI passed a bipartisan effort to increase the minimum wage. That does not automatically mean a similar bill would be bipartisan in DC. It only becomes bipartisan if the sponsor has identified a bipartisan group in Congress that wants to work along those lines.
Either you are naive of you are pretty good at pretending to be. The problem for Republicans wasn't the policy but the politics. Obama himself was eager to have them on board, the health insurance and pharmaceutical companies begged them to take part in the writing of the bill.
But they determined even before Obama was sworn in that they will give him no aid or comfort whatsoever. Their goal as Mitch McConnell proudly said was to make Obama a one-term president and denying him any kind of legislative victory was instrumental to their plan.
If you really think that Democrats backing off on mandate would suddenly make Republicans vote for Obamacare then you're living in a fantasy world. Their opposition was so shameless that even supposedly serious people like Grasssley embraced Palin's rhetoric about "death panels". So don't give me this BS about Obama and the Democrats not being bipartisan enough. Your party decided to blow up the system in order to whip up its base. And today it's reaping the rewards of this strategy in the form of TRUMP and Cruz being the frontrunners for the nomination.
