It's pretty simple....
Repubs want to make the President look bad in any way shape or form. Once again, they mission is to do their best to make Obama a one-term president. And they're doing one great job. They jacked up his health care reform, watered down the stimuli spending, extended the Bush tax cuts, and have still made the President look bad. They've even made many blame the bailouts and terrible economy (and debt) on him (all while forgetting the previous abortion and what his horrific policy was for 8 years).
Yeah, Bush sucked and spent money like it was going out of style. Then along comes Obama and takes spending to a whole new level. Does anybody really think that we should just raise the debt ceiling and go on with business as usual? Remember all the fear mongering we've heard for years about running out of money? Well, we're here now. Without some solid plan to reduce the debt in the future what is the point of raising the debt ceiling now? We'll just hit it again in the near future. Like I said we need a solid plan and as far as I can see, Obama and the democrats haven't produced one. If I was the president (and made all sorts of promises while campaigning about running a transparent government) I would bring in C-span into the negotiating room and let the public watch what is going on. But as we all know, we'll never be privy to the behind the scenes deals that are made.
One last question concerning the budget. Isn't the senate required by law to pass a budget every year? If so, where is the budget for the last 2 years?
