Salisbury steak is better than eating nothing and starving to death.
Except starving to death isn't the alternative in this case. There do need to be cutbacks in spending, and Ryan's voucher plan is one way to achieve that, but to pretend that there will be no difference in the quality of coverage is fundamentally dishonest and the Republican pandering on this point for short-term political gain keeps the necessary reforms (whatever their final shape is) from being achievable because such reforms will need genuine broad-based support.
The dishonest claims that Romney and Ryan make about their own plans are detrimental to the goal of entitlement reform.
