61% of voters think it's likely Obamacare will be repealed.

And 54% favor repeal.

Presumably, that's repeal if the Supreme Court doesn't strike down the law, and 54% expect the Supreme Court to strike down the law, and 50% would like to see that happen. 37% would like the law upheld, and only 26% think that's going to happen. Only 20% of voters think Congress has the constitutional authority to force everyone to buy health insurance.

And here, Scott Rasmussen why the law will die even if the Supreme Court upholds the law and Obama is reelected...

Seventy-six percent [of Americans] think they should have the right to choose between expensive insurance plans with low deductibles and low-cost plans with higher deductibles. A similar majority believes everyone should be allowed to choose between expensive plans that cover just about every imaginable medical procedure and lower-cost plans that cover a smaller number of procedures. All such choices would be banned under the current health care law.
Americans want to be empowered as health care consumers. Eighty-two percent believe that if an employer pays for health insurance, the worker should be able to use that money and select an insurance product that meets his or her individual needs. If the plan they select costs less than the company plan, most believe the worker should get to keep the change.

It's not just the idea of making the choice that drives these numbers, it's the belief held by most Americans that competition will do more than government regulation to reduce the cost of health care. For something as fundamental as medical care, government policy must be consistent with deeply held American values. That's why an approach that increases consumer choice has solid support and a plan that relies on mandates and trusting the government cannot survive.
