As virtually everyone knows by now, there are significant threats of a government shutdown in the US. The basic guts around it is that the US government will run out of funds for daily operations as no appropriations bill has been passed (as of yet). The reason there is no appropriations bill passed is because the GOP wants to defund the Affordable Care Act, and therefore makes defunding it one of the strings it has attached to get what it wants. And there is also the debt ceiling on the way.
Do I agree that the above is irresponsible, petty, partisan, reckless, and obstructionist? Yes, yes, yes, yes, and yes. But guess what, it is perfectly legal. Article 1, Section 5 of the United States Constitution says (in part) the following:
Each House may determine the Rules of its Proceedings, punish its Members for disorderly Behavior, and, with the Concurrence of two thirds, expel a member.
In other words, filibusters, refusing to fund the government, and so on, are all allowed by the rules the two Houses of the United.
Therefore, this means that another takeaway from the (likely) US Government shutdown and debt ceiling crisis is that the rules of operation should be amended to prevent the above obstructionism and hostage-taking from being allowed to occur.
