I probably worry more about the buying of judicial elections than I do about Congress, because the corporate and right-wing handmaidens put into these positions will be around to wreak havoc on a larger scale for a very long time. Via Think Progress, look at the huge amounts of cash they pour into these races:

After the Supreme Court’s Citizens United decision opened the floodgates to unlimited corporate money in American elections, the decision’s defenders claimed this wasn’t such a big deal because unions could also take advantage of the decision. A new report by three leading voting rights and judicial independence groups gives the lie to this claim. According to the report, just three corporate interest groups — The Ohio Chamber of Commerce, the Business Council of Alabama, and the Illinois Civil Justice League spent more than 13 times as much trying to influence state supreme court elections as the entire labor movement.

The report focuses on the 2009-10 cycle, so it does not include the recent Wisconsin Supreme Court race where incumbent Justice David Prosser narrowly defeated a progressive challenger after corporate front groups rode to his rescue with hundreds of thousands of dollars worth of funds.
