Remember what President Obama went after the Supreme Court's Citizens United decision in his State of the Union address:
"With all due deference to separation of powers, last week the Supreme Court reversed a century of law that I believe will open the floodgates for special interests, including foreign corporations, to spend without limit in our elections," Obama said from the House floor, as the majority of the Supreme Court justices sat right below him in the chamber.
So far this year, $24.7 million in independent spending has been reported to the Federal Election Commission, campaign filings show. Unions have spent $9.7 million (or 39 percent of the total), compared with $6.4 million (26 percent) spent by individuals and $3.4 million spent by corporations.
As we know, union money goes 90+% to Democrats, while corporate money tends to go to whoever is in power at the moment.
