If Obama wins the comfortable victory that the polls suggest he will next Tuesday, one question that I'd be interested to hear opinions on is "Was 2012 a winnable election for Republicans?". Will 2012 be seen in retrospect as winnable for either party like 2000 and 2004, or never winnable like 1996 or 2008?
One the one hand the Republicans had the strongest possible candidate from their field, the economy was soft enough, and despite Mitt Romney's generally poor campaign Obama's stumble in the first debate provided the opportunity he needed.
Then again, if re-election campaigns are a referendum on the incumbent, then if Obama wins then how suitable a candidate Mitt Romney was shouldn't matter. The economy was growing just fast enough, Obama ended the Iraq War, got Bin Laden killed, ran a scandal-less administration, and had legislative accomplishments like health care reform and ending DADT.
