Can we pause from our hypomanic poll checkups? Can we stop tweeting about the early vote? Is it possible in the final days of this close election to step back and reflect, if only for a few moments, on the challenges that will face whoever is elected president on Tuesday? I’m as guilty as the next pundit of obsessing over the fight between Mitt Romney and Barack Obama. My nerves are fried. I’ve been freebasing poll crosstabs like an addict. But the fiscal, economic, and foreign policy crises that will likely unfold in the coming months cannot be ignored.
