This just in via Paul Krugman's blog, forwarding Glenn Greenwald's commentary.
The gist of Krugman's comment is that Republicans are hypocrites for using Kerry's rich wife against him while attacking Democrats for bringing up McCain's rich wife. I realize Krugman is a Princeton economist, but he's missing the point.
McCain believes you're not rich until you make $5 million a year; using current Republican standards, you're not a gigolo unless your rich, younger wife is worth more than $500 million. Teresa Heinz checked in at about $700 million; Cindy McCain has to get by on $100 million. It's that simple.
Damn ivory tower academics.
