Across the broader midterm cycle from September 8 through Election Day, Republicans have committed $1.9 billion to advertising compared to $1.5 billion for Democrats. The GOP paid an average of $274 per rating point in key September races versus $201 for Democrats because their spending relied more heavily on super PACs that pay higher media rates. Despite injecting more than $740 million into congressional races since Labor Day, GOP spending has barely shifted polling averages in competitive races, CNBC reports.
