While I'll try to avoid political posts for the most part here (with the election coming it's been hard to keep quiet;), I have to mention this link.
The article is from DailyKos, but is very clear and level-headed. It discusses some political/financial history in a way that doesn't require you to be an economist. McCain had a hand in bringing the economy to the brink it's at now. So please read and consider. Regulations are there to protect the people. Unfortunately the supremely rich have painstakenly removed regulations over time, to the detriment of the taxpayers.
