Ronald Brownstein: “If the economy produces jobs over the next eight months at the same pace as it did over the past four months, the nation will have created more jobs in 2010 alone than it did over the entire eight years of George W. Bush’s presidency.  That comparison comes with many footnotes and asterisks. But it shows how the economic debate between the parties could look very different over time — perhaps by November, more likely by 2012. More important, the comparison underscores the urgency of repairing an American job-creation machine that was sputtering long before the 2008 financial meltdown.”
