ATLANTA – Never have American voters re-elected a president whose work they disapprove of as much as Barack Obama's. Not that Mitt Romney can take much comfort – they've never elected a challenger they view so negatively, either.

Unless things change dramatically, this Election Day will mark a first, no matter who wins. The victor will be a sitting president with a slow economy, 8 percent-plus unemployment and an average Gallup job-approval rating below 50 percent. Or he'll be a challenger who isn't liked personally by a majority of the public and faces notable discord within his own party.

Polls since the nominating conventions show Obama slowly widening a slight lead nationally and in several key states that could decide a close election. And the mere fact that Romney hasn't ever notched a clear lead in polling, unlike previous winning challengers by this point, underscores his struggle to strike a chord with an electorate that isn't exactly enamored with the incumbent.
