@cicerone imposter,
I think, as I read what yall (ci, cyclo and parados) are writing, you are not quite talking about the same thing.
The Republican plan calls for the sale of health insurance across state lines. It seems like a slam dunk to say that this will give all potential customers access to more providers and, therefore, cheaper premiums. That is the idea that ci likes.
I wrote about this in a 10/31 post on the Obama thread. Right down to the SD credit card debacle!
Here is another attempt to explain the problems with the Across State Lines idea.
"...(P)ermitting the sale of health insurance across state lines would undermine all existing protections, which are determined state by state. As Families USA revealed, state consumer protections-particularly in the individual health insurance market-vary dramatically from state by state. As the New America Foundation points out, (the) proposal would eliminate the best protections and bring all states down to the lowest common denominator: (selling health insurance across state lines) would have the ultimate effect of standardizing state regulations to the least restrictive level..."

I think that is what Parados was alluding to and Cyclops echoed.
