Sounds awful. But what does AA mean by "hotel vouchers have already been exhausted"? Does that mean they don't have the physical pieces of paper, in which case they can still reimburse you afterwards? Or do they just mean "Our policy when a bunch of people are travelling on AA and get dumped in a strange city with no place to stay is to give hotel rooms to some of them, because it would cost us more money to give hotel rooms to all of them"? Not providing hotel accomodations is totally unacceptable, and "vouchers are exhausted" is just a euphemism for "If we screw our customers, we make more money than if we treat them right". I would send a letter of complaint to the president of AA with documentation of your hotel and cab expenses.

While supply and demand means that additional bonds being issued will have an affect in theory on the interest rates that bonds pay, the new California bonds are such a tiny, tiny part of the total bond market that issuing them probably affects the interest rate investors can get by buying bonds by something like .000001%. I doubt very seriously that this was any part of the motive for anyone's support of the bond measure.
