Romney didn't attack Obamacare in 2012 because he backed a similar law in Massachusetts when he was governor. That's a big part of why he lost. Romney's speeches, debates and ads failed to communicate his line item vetoes of the final law to a political junkie like me, let alone the average low information voter. Democrats successfully argued that Obamacare was a federal adaptation of Romney's plan in Massachusetts. Romney never successfully rebutted this argument. I think this failure to communicate dooms any comeback. Because of the optics of Romney's initial support for a law similar to Obamacare, Romney was not able to make the most effective argument against it. He could have said we tried this in my state and it didn't work out. I will work hard to repeal it when I'm president. If he had said that, Romney would be president today.
Romney can't convincingly argue that we need to limit government because he believes government can do the job if it's under better management. Romney in 2012 proved that he can't turn out the Republican base, even against Barack Obama, the most left wing and incompetent president ever. I don't see how any of this is going to be different in 2016 against Hillary the Inevitable or Elizabeth the Native American Princess. Jeb Bush is out of touch and has 100% bad name recognition. Scott Walker or Bobby Jindal or Mike Pence or even Chris Christie would be a much better choice.
The current occupant of 1600 Pennsylvania Avenue thinks he can rule by decree. If you believe that the president can decide not to collect taxes that are levied by law, as our Dear Leader did with the Employer Mandate taxes, then it makes sense you think I'm needlessly paranoid. Enjoy the unilateral legalization of all illegal immigrants complete with instant welfare eligibility, coming soon after the election without benefit of Congress. For the survival of the rule of law in this country, we really HAVE to win in 2016. Let's not recycle our losers.
