That's not really how it works either. Bondholders usually trust the ratings agencies (this trust is often mandated by law for pension funds, etc.) which have often basically lied about ratings because they were paid by the issuer.
When challenged on this they usually claim the first amendment (i.e. license to lie), although S&P went a step further and downgraded the US in a fit of rage when the SEC started investigating them for ratings fraud in 2011. Ironically interest rates on US treasuries went slightly down afterwards.
The entire rest of the market (and the other ratings agencies) were just about able to determine that if you have the keys to the cash printer you're actually not in danger of running out of cash and political bickering doesn't translate into risk of political suicide.
The white house and congress was deadlocked, the government was shut down, and the treasury was not legally authorized to borrow more to make payments. There was talk of a trillion dollar coin to side step the national debt cap. This was a really big deal, and people were scared the maneuvering wasn't going to work in time. It totally justifies a small credit rating downgrade.
Oh come on. This is partisan hackery. This "theatre" did in fact cause vital government functions to shut down. I was personally on a project where I had to stop work because our checks were sitting on a table in Washington and a major milestone meeting was canceled because the government was furloughed and would not be there, throwing the entire project schedule off. This was replicated thousands of times across the economy.
Even the ghost of a chance of going down to the wire as to whether a bond payment would be missed by a single day on US obligations, is in itself tremendously disruptive. The economy is structured around U.S. debt as being the safest paper there is. Don't downplay just how dangerous dicking around with this for partisan points was.
No, playing up the fearmongering as you are doing right now is partisan hackery. The main Democratic talking points centered around fearmongering, after all, which was almost as stupid as the Republicans temporarily shutting down the postal service, etc. in a fit of pique.
As I said before: the markets correctly characterized the debt ceiling negotiations as a bunch of drama queens on both sides of the political divide acting up & a storm in a teacup because neither side is politically suicidal.
However, a fair number of tea party members in congress were actively promoting defaulting on the debt. That's different than some random guy with a page on the internet. That's a lawmaker with a vote who can affect the outcome. So their political career would be hurt. The election wasn't the next day, it would have taken a long time to replace those yahoos and the damage would have been done. Examples:
You are right sir. And after the ratings agencies downgraded US debt, they actually appreciated in value. Because anyone who understands government finance knows that issuer's of currency cannot default on their own debt instruments unless they want to.
