Romney has repeatedly claimed that Bain helped create 100,000 jobs. Ryan Lizza says that "Romney’s success depends on whether that job-creation statement withstands scrutiny":
Romney has made a similar mistake to the one the Obama Administration made in early 2009, when two of Obama’s economists released a study with overly optimistic unemployment projections. Ever since then, critics have been able to point to that study as evidence that, if judged by Obama’s own standard, his stimulus has been a failure. We could end up with a race that pits Obama’s stimulus record against Romney’s Bain record. Judging from the gleeful reaction of Democrats this week, it’s a debate Obama would welcome.
Chait explains how a Romney-Obama matchup would fuel a debate about class:
The GOP Establishment’s deepest and most recurrent fear is an open debate over economic class. This is not a debate they feel they can win even among Republican voters, a majority of whom actually favor higher taxes on the rich. Romney’s assertion … that economic inequality should not be discussed, or should only be mentioned in "quiet rooms," is a too-frank expression of the GOP elite’s actual belief that the issue must be kept out of political debate.
