Thanks to his exceptional luck in drawing Mitt Romney as his opponent, Barack Obama will probably win a narrow reelection despite the dismal recovery. But on Wednesday morning, a struggle begins within the Democratic Party to save him (and us) from himself -- to keep him from agreeing to a budget deal that will only slow growth, needlessly sacrifice Social Security and Medicare, and make the next four years much like the last four years. What a waste, what a pity. Democrats should be resisting the economic lunacy and political sway of an extremist Republican Party. Instead, they will be working to keep their own president from capitulating to fiscal folly.
