Hi Amos
That percentage above you gave is near the same as the percentages that Reps recieve from big oil companies, this year is 84% to16%.

"Since 1990, Big Oil has given more than $190 million to members of Congress and 75% ($142,635,314!) of those donations have gone to Republicans.1 That money has guaranteed energy policy that serves the oil industry rather than the public interest".

Funny how that scale keeps tipping more towards one than the other.
