From Paul Krugman, writing for the New York Times:
If you want to understand the trouble Republicans are in, one good place to start is with the obsession the right has lately developed with the rising disability rolls. The growing number of Americans receiving disability payments has, for many on the right, become a symbol of our economic and moral decay; we’re becoming a nation of malingerers. ...
What strikes me, however, isn’t just the way the right is trying to turn a reasonable development [the increase in disability rolls] into some kind of outrage; it’s the political tone-deafness.
I mean, when Reagan ranted about welfare queens driving Cadillacs, he was inventing a fake problem — but his rant resonated with angry white voters, who understood perfectly well who Reagan was targeting. But Americans on disability as moochers? That isn’t, as far as I can tell, an especially nonwhite group — and it’s a group that is surely as likely to elicit sympathy as disdain. There’s just no way it can serve the kind of political purpose the old welfare-kicking rhetoric used to perform.
