Now Obama has to hope the GOP doesn't play ball and pass this. Because this isn't a job maker, it might not even stave a recession off at all. If that happens, Obama's ass is in a sling.
If this passes on a broad bipartisan basis I think it'll do a lot of good for the economy indirectly- renewed confidence from seeing strong Presidential leadership and a bipartisan Congressional effort to fix the country will greatly break the "mental recession." Also, especially cutting the payroll tax in half for everyone will definitely drive up consumer spending.
Because the early 2008 stimulus really helped the economy and lifted consumer confidence.
