I wrote an op-ed in the Sac Bee, which you can find here.
Here is a portion of the first paragraph:
An unlikely government agency, the Securities and Exchange Commission, may help to stem the tide of undisclosed money pumping through our
political system in the wake of the U.S. Supreme Court's 2010 decision
in Citizens United v. FEC. The SEC is not the first government agency
that comes to mind when thinking of campaign finance regulations.
