Congressional approval is certainly not at 90%, but I believe what gugi means is that voters usually support their own Congresscritter and hate everyone else's, or Congress in general. I believe, however, that this upcoming election is one of the first where even the average of the support for one's own Congressperson is below 50%. Support for the Congress in general has been bouncing between 10 and 15% since at least the middle of Bush's second term.

And people are gullible, which is why it's important to have laws and police in place to protect people from being taken advantage of due to the sorts of gullibilities we know about and can protect against. Imagine if the wholesalers of the Gold Dollar razors and Kreigar razors were able to sell their wares in the Vendor's section here, make posts all over the forums about how great their products are, and harass and sue the people who make valid critical posts about their products, even if they never win those suits on the merits. How many people would get scammed into buying trash, and how much would the community be hurt by it if that were allowed, because of newbies who got frustrated and quit, instead of buying more razors from reputable traders, refurbishers and manufacturers, to say nothing of the strop-makers and the soap-makers, or sticking around to provide support for the next generation of newbies?
