As a long-time san francisco resident and close observer of the politics, I'm going to take the liberty here of speaking for what I think is the dominant sentiment that will prevail if SF gets the bid. Not the anti-Olympics people who exist in every city and are just a vocal minority ("What a bother! The traffic, the crowds! Yuck!"), but rather the vast majority who show up on parade day when the Giants win the World Series, and so on. Here goes:
We are a city of very fit, outdoorsy people who like sports (especially when our team wins) and we love a good party. We are great fans for the SF Giants and 49ers (even though the latter sort-of left us), and the Warriors will be welcomed back enthusiastically into their new arena. Our stadiums and arenas get built well and usually sell out. We are happy to have a ballpark/arena/regatta/(and yes) Olympics in our city, as long as we don't have to pay for it. We know that the bay area is swimming in private money, which can easily cover the costs of these things. That's what we insist on, and if private money builds it, we will come, we will cheer, and we will have a great time. OTOH, try to dip your hands into our treasury and we get very cranky. We are needy, with lots of transit projects in the pipeline, homeless and disabled people, underfunded schools, a health program that is supposed to cover every resident who doesn't have their own insurance, and a housing shortage. Unlike New York City, we are barred by our state's laws from having our own income tax, and we live with a state and federal government that often appear hostile to us. So just realize that we have a lot on our plates and we need our public money for our own needs. But the truth is that we would love to have the Olympics if it can be done without hurting our finances, and we will be good volunteers and do a great job with it if we get it. Thanks.
