Derek Thompson points out that Romney's "secret admission" on the 47% is a standard Republican talking point:
Mitt Romney's off-the-record comments were inelegant. But they were also part of a long trend of Republicans attacking the 47% as lazy, or playing by a different set of rules, or not fully contributing to the country. Michele Bachmann went after the non-payers. So did Rick Santorum. And Sen. John Cornyn.
Dave Weigel picked up on something similar at the Values Voter Summit, when asking its attendants why Obama might win:
The single most common answer? Well, Obama's Democrats have been pumping up the ranks of the poor with free goodies, and those saps might be numerous enough to vote for him. They'd been hearing that on talk radio for, well, years. "We have 47, 48 percent who pay no income taxes," said Rush Limbaugh in July. "We have 3 million more off the unemployment rolls and on the disability rolls, and they all vote!"
Of course, as Dylan Matthews pointed out yesterday, this isn't true:
[P]oor people actually don’t vote that often. According to a CNN exit pollin 2008, those making less than $15,000 a year made up 13 percent of the population but just 6 percent of voters, while those making more than $200,000 a year made up just 3.8 percent of the population but fully 6 percent of voters.
