Michigan saw one of the widest disparities between broadcast spending and airings. Democrats aired more ads than Republicans (9.4K to 8.0K), despite Republicans outspending them $23.6M to $14.6M. Outside groups accounted for 85% of Republican broadcast spending in the final week, compared to 53% for Democrats. This disparity is particularly significant during the election window, when candidates benefit from lower unit rates on broadcast advertising, allowing their campaigns to secure airtime at lower costs than outside groups.
