Obviously the Democrats are also subject to greed!
Obviously they also receive money from some big corporations!
But I'm not sure if the "payback" is as bad. . . because, Republicans just "buy in" that "elite are better" crap. . .Democrats are a little bit more sceptical and will be glad to take the money, then many still vote their conscience.
It's simple. . .why do you think ALL the GOP Congress member vote EXACTLY the same thing. . .while some Democrats do find the courage (for better or worse) of voting away from party line?
Obama made out very well from Wall Street anf Fannie Mae even as a junior senator from Illinois. They seem to have gotten their money's worth. the GOP vote uniformly on terrible measures, not so on others.
