Public Citizen put out a post-election report that looked at spending by third-party organizations that can take unlimited contributions and do not have to disclose their donors in all of the races in which a seat in the U.S. House or Senate changed hands from one party to another.
In the 74 races where that happened, the winner received more support from those groups than the loser in 58 of them. But Michigan’s District 7 bucked that trend. Because of a rush of last-minute spending, Rep. Mark Schauer (D) got $877,098 more help from those groups than Tim Walberg (R) did.
District 1, the other key House race everyone was watching, held more to form. In that race, Republican Dan Benishek received $355,178 more in help from such organizations than his opponent, Democrat Gary McDowell.
Most of that spending was on so-called “issues ads,” which typically are negative ads about one of the candidates in the race that don’t explicitly tell viewers to vote for their opponent.
