We know people have issues with polling in general and with Frank Luntz in particular, but sometimes survey results are just too important to ignore.

To wit:

In a poll that will appear in Playboy Friday, Luntz says that more Republicans than Democrats have sex at least once a week. Fifty-five percent of Republicans but only 43 percent of Democrats report hooking up at least weekly. On the other hand, 67 percent of Democrats but only 51 percent of Republican say they've watched porn with their partners.

Do Republicans and Democrats see eye-to-eye on anything sexual? Yes. Twenty-three percent of Republicans and 24 percent of Democrats say they'd probably have a one-night stand with a president if they found that person physically and sexually attractive.

Which presidents fit that bill? Luntz's respondents overwhelmingly picked Bill Clinton as the sexiest president of the past 40 years, with Ronald Reagan a very distant second. The least sexy president? Richard Nixon, with Clinton second.
