It could possibly be the Presidential Election Campaign Fund donations (the little box we can check on our taxes if we want to donate $3 to fund the scam elections). Personally I’ve never checked it because I would rather light $3 on fire. I’m not sure if it can be used in midterms, but apparently it can be used for minor party nominees:

Just a thought. Either way it’s a total shake down of the American taxpayers.

Edit: never mind. I guess a “minor party” is someone who runs for President and just doesn’t get as many votes as the “major party”:

Maybe there’s a State Tax version of the check box for state races?
