Mitt will do essentially nothing to solve the approaching fiscal crisis, and Barack will do even less. But if we drive off the cliff and a Republican is in the White House, the electorate will immediately claim that because the crisis went unsolved, Romney was obviously too extreme a right-winger and will tarnish the name of fiscal conservatism for decades.
Better off in four years? Romney, by a miniscule margin. Better off in the long term? Obama.
