Interesting observation: for everybody who wishes that people could come together from all political sides to pass laws, your wish has been answered. This list includes characters from every part of the political spectrum.
As the saying goes, we have an evil party and a stupid party. Every once in awhile, they work together and produce public policy that is both evil and stupid.
I like this because it accurately reflects the customers -- voters -- views, yet it is also completely non-partisan. My party is always the stupid one, the other party is always the evil one.
In this case, several of the folks are prominent representatives of their party. Guys we might see on TV explaining to us why policy X is good and policy Y is bad.
Paying for laws is done this way -- buying off the prominent members -- so that the status quo is maintained, i.e., I still keep thinking my guys are acting stupid and the other ones evil and you keep thinking the other way. If it had only been lesser members sponsoring, it wouldn't work that way.
