I used to like John McCain, too, but I must admit that was because he was bucking his party to do things I agreed with. I would not have had that reaction if, say, Bernie Sanders decided to rebel out of principle and support privatizing Social Security.

One line I’d draw would be on raising the eligibility age for Social Security and Medicare. It sounds fair, since people are living longer. But it isn’t. Lower income workers are the ones who find it hardest to keep working after 65. And they’ll get penalized with lower benefits.
