A Hypothesis about the Effect of Citizens United
From a grad student in our department who used to work at the FEC:
> Anecdotally, of the 300 committees I reviewed at the FEC, only one
> corporate PAC made independent expenditures over $5000 in the 2008
> election and it was the Human Rights Campaign, which is a non-profit
> corporate PAC. The rest were unions (AFSCME, SEIU, etc.). I think
> labor unions are going to take much greater advantage of the decision
> than corporations - especially when it comes to things like GOTV
> drives and voter contact communications. I think the types of
> corporations that will get involved with that type of activity are the
> non-profit interest groups (Human Rights Campaign, NRA, Chamber of
> Commerce, etc.) as opposed to for-profit corporations like Goldman
> Sachs and Bank of America.
