A government shutdown could result from one side being obstructionist, or from either or both sides being particularly stubborn.
The difference to me is between this type of of dialog:
D: We want a 40% tax rate
R: We want a 20% tax rate
D: We can maybe go down to 35%
R: We can maybe go up to 25%
(both sides then refuse to budge)
(eventual government shutdown)
Vs this:
D: We want a 40% tax rate
R: We want a 20% tax rate
D: We can maybe go down to 35%
R: We want a 20% tax rate, plus we insist that one city in every state be named after Ronald Reagan
(both sides refuse to budge further)
(eventual government shutdown)
Part of what makes this a tricky issue, one worthy of starting a thread, is that as others have pointed out, few if any individual occurrences are proof of obstructionism. After all, it’s the role of the opposition party to be stubborn and stake out positions that are at odds with what the majority party proposes. The question is what happens next… whether compromise is desired and worked for.
Simplifying greatly for a moment, if you imagine that all positions are just numbers, then a functioning government is one where if one side starts out at 9, and the other starts out at 6, the end up actually passing the law at around 7.5, maybe weighted towards whichever party controls more of the branches of government. Obstructionism then would be either absolutely refusing to budge, or claiming that you want 4, even though up until last year your party wanted 6, but now if you request 6, then the other party might agree on 6, and you’d rather just have a disagreement, which you can then blame on the other guys. But of course it’s very hard to convert complex real positions to numbers like that, particularly in any objectively provable sense.
