Do you sometimes get the sense that the presidential campaigns’ online operations are hurting more than they’re helping? Case in point 1: On the day that dismal job numbers are released the Obama campaign releases a video featuring Anna Wintour, the editor of “Vogue.” Case in point 2: The Romney campaign makes three spelling errors in its online offerings: “sneak-peak,” “offical,” and “Amercia.” Both cases speak to a larger mistake that both camps seem to be making: the assumption that their candidates are beloved, iconic brands.
