Those poor politicians, we can't expect them to read laws before voting on them. They must of gotten confused because they have so many checks to cash and speaking gigs to preform.
It's the same argument you hear from businesses and affluent individuals: "If I don't [pay my employees as little as possible | take advantage of every tax loophole I can find | spend thousands of dollars lobbying congress | pollute the environment], my competitors will."
Of course, those excuses ring hollow when those same individuals aren't in favor of changing a broken system. Any politician that complains about fundraising but is not in favor of campaign finance reform is a hypocrite, IMHO.
Who's in charge of setting up the system again?
