Who are the ‘undecided’ voters? And what the heck are they waiting for?

Saturday Night Live” has mocked them. Tony Kornheiser has said he “loathes” them. Partisans — and many political reporters — wonder just what the heck they are waiting for.

The “they” of course refers to that sliver of people who say they remain undecided in the 2012 presidential race. With four weeks left in the campaign, winning over these voters is a critical last piece of the electoral puzzle for both President Obama and former Massachusetts governor Mitt Romney.

All of which points to a simple question: Who are these undecideds and what, exactly, do they want to hear that they haven’t heard yet from the candidates? [cont.]
