Democrats seize air supremacy in Senate battlegrounds

When it comes to winning US Senate races’ television ad wars, Team Blue has seized the advantage a month before Election Day.

Democratic candidates and their liberal allies aired more TV ads than their conservative opponents in seven out of nine top battleground states, according to a Center for Public Integrity analysis of preliminary estimates from Kantar Media/CMAG, an advertising tracking service. Democrats proved particularly dominant in the US Senate races being waged in Alaska, Georgia, Louisiana and Michigan, where they bested Republicans by sponsoring hundreds more TV spots throughout each state, the analysis indicates.
