Conservative super PACs have far outpaced their liberal counterparts in 2012, according to an analysis by the Center for Responsive Politics. Liberal super PACs spent a total of $31.1 million through the end of July while conservatives spent $137.1 million. In spite of modest gains in liberal super PAC spending, conservative groups have kept a steady lead. Conservative superPACs spent $27 million in July alone, nearly as much as the total amount spent by liberals.
The analysis also found that the top conservative SuperPACs, Restore Our Future and American Crossroads, rely heavily on funding from Wall Street and the chemical industry. The top liberal super PAC, Priorities USA, received most of its donations — $5.1 million — from the entertainment industry. In contrast, Restore Our Future received $26.1 million, more than Priorities has raised total, from Wall Street.
