First, even assuming everything said in the article is correct, those Republicans criticized for being concerned about public opinion (Boehner, etc.) will remain concerned about it because they'll be thinking ahead to the 2014 and 2016 elections. So the dynamic that supposedly would be improved by an Obama win won't improve.
Second, if Obama wins, they'll be recriminations going both ways. As much as those conservatives who prefer Obama to Romney may want to believe they are the "only" conservatives, there will be plenty of other conservatives who will blame the "I'll take my ball and go home" crowd for an Obama victory.
Third, Obama will almost certainly be able to seize liberal control of the Supreme Court, which will have consequences that can't be undone at the next Presidential election.
Oh, and fourth, and Obama win might well result in voting/union, etc. laws being changed to the point where future electoral victories by conservatives become structurally impossible.
The only people who "win" by Obama getting reelected are leiberals, and those conservatives who would rather claim rhetorical victories than help the country.
Good points but what’s your plan if Romney loses? Hopefully, it will be to demand that Republicans finally fight.
