Mitt Romney and Paul Ryan have explained repeatedly that their reform proposals would never reduce Medicare benefits for Americans over 55-- who have paid into the system throughout their working lives.
Even changes for younger citizens would be optional – offering more, not fewer, choices for those who want added insurance flexibility, and saving money for a bankrupt system. Democrats who attack Paul Ryan for—in the famous ad—wanting to push Granny off a cliff are exactly wrong: Ryan at least authored a sweeping plan to rescue Granny by providing long-term funding. Demagogic Democrats propose no meaningful changes, beyond grabbing $750 billion from Medicare for the elderly and using it to fund Obamacare for the young and middle aged.
The only sure way to kill Medicare and to leave millions desperate and destitute is to keep racing down the current unsustainable path.
