Vacationing Russian Prime Minister Vladimir Putin has stoked his macho image once again — appearing in photos and video in a series of athletic, outdoorsy scenes — on horseback, with fishing pole in hand, taking a swim. Of course, Putin is not the first world leader to appear sans shirt. President Obama was famously photographed catching a wave in Hawaii just a year ago. And with Putin raising the pin-up stakes, all eyes will be on Martha's Vineyard later this month — when the American President may yet respond. But tonight, we ask: Should those who hold high public office show a little more decorum? Or is perfectly acceptable to show some skin? Tell us what you think.
