Local and national broadcast TV will continue to receive the overwhelming bulk of all ad spending during the upcoming primaries and presidential race.

According to TNS Media Intelligence, only a small portion of budgets will go to cable or digital platforms, Ad Age reports (via MediaBuyerPlanner). "I know there's a lot of talk…about the potential for cable, the potential for the internet, but ultimately at the end of the day, television is the biggest megaphone that these campaigns have," said Evan Tracey, chief operating officer of the Campaign Media Analysis Group at TNS Media Intelligence.

Advertising for state and national political candidates and related issues could go as high as $1.6 billion this year, TNS said. Last year, TNS said spending for this year's midterm election could reach as high as $1.7 billion.

Last month, Campaign Media Analysis Group, a TNS Media Intelligence company, reported that from Jan. 1 - Aug. 13, 2006, $311 million had been spent on local television by candidates, political parties, and interest groups campaigning within the nation's gubernatorial, congressional, and senatorial elections - a 150 percent increase over the amount spent during the same period in 2002.
