For not being a citizen you have some strong opinions about his alignment being "nonsense." Basically, republicans have utilized the increasingly deregulated campaign financing (via Super PACs) to a much later extent than Democrats. The key figure on this page[1] is on the unlimited donations category, which largely comes from the rich, old or not. I think this article[2] describing the upwards redistribution of wealth by the right might also surprise you.

EDIT: Also, even more to the point, it's been a conservative court than has unspooled campaign finance regulation to the point where Lessig felt obligated to step in.
