Don't for a second believe that a politician is destined to lose re-election simply because he has been an unmitigated disaster. That would be unfair to your senator or your congressman, and it certainly wouldn't be fair to countless two-term presidents. Any elected official can overcome self-induced failure with a little help. And as David Harsanyi observes, the Republican Party seems determined to give President Obama all the reelection help he needs. Given the GOP's deeply flawed slate of primary candidates, Harsanyi writes, Obama can win a second term.
