Sure Republicans love furrowing their brows and kvetching about "entitlements." EVERYBODY in Washington does. It's how one demonstrates membership in The Very Serious People club, how one gets Dancing Dave to do a bit of gangnam in your honor. But in truth Republicans just don't care about cuts to Social Security. Sure they'd scrap the whole system if they were your malevolent dictators, but they aren't. Old people vote, they vote Republican, and risking the wrath of their voters over Social Security isn't worth hiking taxes on Jaime Dimon by one penny.
Having Democrats OWN cutting Social Security, that's a different story....
