Republican are miscalculating by celebrating the weak economic report. As you might have already seen, the latest Gross Domestic Product report showed the nation's economy shrunk by 0.1 percent in the fourth quarter of 2012, the worst economic performance since 2009. This is not a good number, so naturally Republicans are thrilled: The bad GDP news makes it even more unbelievable that Obama has been ignoring job growth in his 2nd term agenda.
