All Bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills.
http://en.wikipedia.org/wiki/Article_One_of_the_United_States_Constitution#Clause_1:_Bills_of_revenueProgressive legislation that incurs a tax must first be originated by Congress. If the Administration loses the House of Representatives, it will be
extremely difficult to enact that new legislation. Want to have a second stimulus? There's no way a Republican held House would allow it, even if the Administration attempted to pull a Bush Bailout coup and try to dance around this Constitutional requirement.
From my POV I cannot comprehend a second stimulus being able to be passed if we lose the House of Representatives. While this may bode well for an Obama reelection (the Carter position), I really would hate to see the country fester for another 2 years or possibly even more if we cannot get the House back and retain the Presidency. This is important, guys and gals.
