In the waning days of the campaign, Freedom Works dumped more than $1 million into the 8th congressional race to stave off a challenge to Joe Walsh from Democrat Tammy Duckworth.
In all, the SuperPAC plowed nearly $3 million into the campaign.
Ultimately, it didn't pay off. Duckworth beat Walsh by 10 percentage points.
Elsewhere, Freedomworks has a "low batting average," according to opensecrets.org, which ranked it the sixth top-spending super PAC this election by plowing $19 million into campaigns.
