Tampa, Florida - If you were watching the local evening news on Tuesday, chances are you saw an ad for either Barack Obama or Mitt Romney.
In fact between 5 p.m. and 6:30 p.m. on Tuesday, a total of 48 ads for the presidential candidates aired on the four Tampa Bay local network affiliates; WFLA, WFTS, WTSP and WTVT.
University of South Florida Professor of Political Science Dr. Susan MacManus says the barrage of ads is a sign of things to come.
"There's going to be non-stop spending because the polls show this race to be a tight one and it's going to go down to the wire," MacManus said. "The way you get your message out is you have to spend money and a lot of that is on TV."
To date, MacManus says both candidates and their supporting super PACs have spent $22-million on television ads between the Tampa/St. Petersburg and Orlando markets.
"Just think of that and it's only July," she said.
According to the Washington Post, $61 million dollars has already been spent on television ads in Florida. That total leads the nation.
The candidates and their super PACs have spent another $59 million in Ohio. Virginia, Pennsylvania and Michigan have also seen ads buys in recent weeks, but most of the states have yet to see a TV ad for either candidate.
Most of the ads currently airing are also negative attack ads, which MacManus says can always turn some voters off.
She says both Obama and Romney will need to be careful as they continue spending massive amounts in areas like the Tampa Bay.
"It's just overwhelming to many, many people who see it as almost immoral at a time when people are suffering so economically that so much money is being spent on these campaigns."
