Romney will lose.
The goal has to be to get strong conservatives in the House/Senate to prevent too much damage from Obama’s second term.
(Indeed, the goal would be same even if Romney had a chance, given that he’s Obama-white.)
If Obama were playing US politics, this approach would work. Obama does not view himself as President, he intends to lead a revolution which will overthrow the US political system. Think more along the lines of Russia's second revolution, or Hitler's machinations to gain ever more power and establish the thousand year Reich.
Obama and company are thinking in Hegelian, world historical terms and the longer he stays in power, the more his followers will infiltrate the government, subvert the legal system, and undermine the rule of law. Already he has Congress bamboozled. He daily creates laws though Imperial fiat (EPA standards, IRS regulations, DOJ, DHS, and INS selective enforcement, etc.) He usurps constitutional authority concerning war powers, he avoids 'advise and consent' powers by appointing czars and making recess appointments. His goals are not driven by political ideology, although he is Marxist ideologically, and he uses ideology to motivate his base, obfuscate issues, and hide his true intentions.
His only ambition, and the end game in Obama's strategy, is power. Absolute control of the state in a fashion enjoyed by Chavez, or Castro. Absolute power obtained by the means employed by Lenin, Stalin, and Hitler.
Congress hasn't even slowed him down. They issue a subpena, his people ignore it. He wins every round of the 'blame' game in the press. And by 2016 he will be installed in such a way that he will never be removed.
Good luck on Congress or SCOTUS thwarting his plans. Half of them are complicate, the other half don't even know the rules they are playing against.
