This excellent article has details about both McCain and Obama's campaign contribution connections to Wall Street, including some of the firms now getting bailed out by ... you and me and other taxpayers.
Twisted campaign commercial banter notwithstanding, it's clear to anybody that their is a very questionable relationship between campaign contributions and legislation. It's not that Obama or McCain have some sort of quid pro quo with contributors - they do NOT have that. However, it's clear that contributions help keep supporters in power and keep those to whom they contribute within earshot, key reasons companies spend so much on politics.
Like pigs with lipstick, the campaigns and foolish journalistic lackeys failing are failing to discuss or report about the key issues in the race: A Challenged Economy and looming home equity disaster, war and global hegemony and dangerous adversaries, and massive Government Spending. Unfortunately clear thinkers won't find a candidate with good ideas about all these things. Where are the founders when you need them?
