Yes, just when you thought it was safe, Congress has decided to return to Washington, DC and start in again on that legislating thing they like to try to do. September is always, ummm, interesting, because September 30th marks the end of the fiscal year. As such, Congress is supposed to have all the appropriations bills for the start of the FY08 completed.
As of now, they have 0 completed. Yes, that's Zero. Nadda. Nothing. (For the current status of Appropriations bills, check out the Library of Congress' Thomas website.) Everyone fully expects what's known as a continuing resolution will be passed near the deadline date (perhaps one of several). This approach will basically allow the government to function at its current rate of spending until such time as the official appropriations bills are completed.
Now, before you get to ticked off at your legislators, bear in mind that the appropriations process is NEVER EASY. Imagine in your own life having to create a budget for your household with the agreement of 535 of your friends, family and complete strangers from all around the country. The people assigned to your budget from California might, for example, think that spending money on hot tubs is important while those from Texas might want more money to go to household fuel (the oil and gas state? get it?).
Before you could start spending money, you would have to get all these people (or at least 1/2 of them) to agree on priorities. Yes, it's their job and they should be able to get it done. But remember: it's a tough job. So have a little mercy.
