Romney Campaign Makes $12 Million Ad Buy The Romney campaign, flush with cash from its impressive haul of $170 million last month, is reserving large quantities of airtime for the coming week. In one of his biggest ad buys of his campaign so far, Mitt Romney, the Republican nominee, has booked about $12 million worth of television advertising for a six-day rotation of commercials that will begin on Wednesday. The ad buy - timed to start the day after the second presidential debate - will cover both cable and broadcast television in nine states: Colorado, Florida, Iowa, Nevada, New Hampshire, North Carolina, Ohio, Virginia and Wisconsin. The biggest amounts will be spent in Ohio (about $2 million), Virginia ($1.5 million) and Florida (more than $3 million). The advertising onslaught coming from the Romney campaign only adds more political noise to the thoroughly saturated airwaves in battleground states. From now until Election Day, candidates and "super PACs" have set aside more than $83 million for advertising, all of it concentrated in 10 states. Michigan is the one state where neither campaign is advertising, despite the efforts of a pro-Romney super PAC there. And the barrage of ads is only going to get heavier. The Romney campaign typically books its advertising time only a few days in advance because it is wary of tipping its hand to Democrats. But with so much money at its disposal - and a group of top advisers who have long said the election will be decided in the final days of the race - the campaign is certain to buy heavily over the next three weeks. Commercial time in many states like Nevada, which is the epicenter of the 2012 political advertising binge, has been completely bought out on some programs. Las Vegas is the most saturated media market in the country, data from Kantar Media show. Cleveland is No. 2, followed by Denver, Reno and Columbus, Ohio, rounding out the top five.
