Mitt Romney seems to think Americans aged 54 and younger aren’t smart enough, or don’t see far enough into the future, to vote now to keep Medicare in their old age.

Under the Romney/Ryan plan, people born after 1957 would get a limited-value voucher to put toward the purchase of private insurance. The voucher won’t cover the full cost of care, which means you’d be stuck paying a growing part of your health care costs, which means you’d be more likely to forego screenings, treatments, and medications, and wind up even sicker.
