I do agree with you that this helps frame the debate around the what Republicans view as an ideal plan. In hindsight what President Obama should have done is embrace the Debt Commission's plan regardless of if it garnered the necessary votes and push that as the starting point. Instead now everybody is using Ryan's plan as that baseline.
Technically, no Republican budget will be able to be signed into law until 2013. Even then that depends on winning the presidency, maintaining their hold on the House, and gaining a substantial numbers of seats in the Senate. Getting all three is doubtful in my opinion.
For anyone that supports Ryan's plan I do have one question. How will adding elderly to private insurance decrease the cost of health care insurance? From what I have see from insurance companies they are already worried about their ability to make a profit if they need to insure the elderly, the costliest group to insure. If that is indeed the case, then what is stopping insurance companies from just raising the costs of everybody's insurance premiums to cover the money they most likely will lose from insuring the elderly?
