Club for Growth Action, the campaign arm of the anti-tax group Club for Growth, is one of the rare super PACs that spends to defeat both Republicans and Democrats. Launched in August 2010, it has spent $12.2 million on the 2012 campaign cycle, mainly to defeat Republicans viewed as not conservative enough (RINOS, or "Republicans in Name Only").
The Club for Growth, and affiliates such as Club for Growth Action, shocked the GOP establishment by funding primary challengers against Republican incumbents at odds with conservatives on tax and spending issues. Club for Growth Action spent $947,991 to defeat six-term Sen. Richard Lugar (R) of Indiana and nearly $5 million to derail the GOP establishment favorite to replace retiring Sen. Kay Bailey Hutchison (R) of Texas in a May GOP primary.
So far, it has spent $9.2 million against Republican primary candidates, $803,342 against Democrats in the general election, and $2,161,559 in support of Republicans in the general election. The group has raised $13.8 million.
The donations made to Club for Growth Action are typically much smaller than donations made to other big super PACs; the largest was made by Virginia James, an investor from New Jersey who gave the group $1.35 million.
