The “super PACs” and secret-money groups that polluted this year’s election with hundreds of millions of dollars’ worth of largely ineffective attack ads are not slinking away in shame. Many are regrouping and raising more money for a task that is no less pernicious: lobbying Congress and the White House on behalf of their special-interest donors, using the new, anything-goes rules of super PACs to make their advocacy more powerful.

Americans for Prosperity, the so-called social welfare group founded with the support of David and Charles Koch, spent at least $36 million this cycle in a largely fruitless attempt to defeat Democrats and elect Republicans. Now it is joining with other conservative groups to lobby Congress not to raise taxes in the current negotiations over the “fiscal cliff.” The group is also demanding there be no reduction or delay in the budget sequester, the widely loathed measure that, in January, will begin cutting $1 trillion in spending over a decade.

It will be joined in that effort by the Club for Growth, which spent $19 million to elect Republicans; by Americans for Tax Reform, led by Grover Norquist, which spent almost $16 million; and by the American Crossroads groups, founded by Karl Rove, which spent $175 million. None of the candidates Crossroads supported won their races, but, nonetheless, the groups are planning a new lobbying and advertising effort on the fiscal cliff, as well as energy and health care issues, according to Roll Call, the Capitol Hill newspaper.

It’s bad enough that these groups and their wealthy donors, many of them secret, missed the message of the election, in which voters rejected their stridency and supported policies like higher taxes on the rich. But by combining lobbying with lavish campaign donations, they are enhancing the danger of the unlimited-spending era.
