With Newsweek going out of print in 2013, the question of which magazine will carry on the tradition of headline-grabbing covers must be asked.

Bloomberg Businessweek has already emerged as a potential answer, with last week's provocative global warming wrapper, and this week's "four years later" photoshop by Justin Metz.

Will Obama really age that much in four short years? History suggests he might (see left, click to enlarge).

But the cover is less of a prediction and more of an illustration of what the kinds of difficulties the president faces might do to his facade.

"The opposition remains considerable, and no matter how successful he is, the hardest job in the world will take its toll," the magazine says.

The real question, therefore, must be: "In four years, will Lena Dunham still want to bounce quarters off the president's butt?"

(BTW, if Romney would have won, Businessweek was ready to go with this cover:)
