Cosmopolitan magazine, which featured nude photos of Republican Scott Brown as a young law student, is backing his Democratic opponent  in New Hampshire's U.S. Senate race, saying Brown's policy positions "just aren't as solid as his abs were in the `80s."

The magazine endorsed Sen. Jeanne Shaheen on Tuesday, calling her one of the nation's most vocal and active leaders on reproductive freedom and other women's rights issues. A former governor, Shaheen is running for re-election against Brown, a former Massachusetts senator who moved to New Hampshire last year.

Brown did a nude centerfold for Cosmopolitan in 1982 after winning the magazine's "America's Sexiest Man" contest. He was a 22-year-old law student at the time.
