Trump, Biden funnel ad dollars into key battlegrounds in final stretch

According to a Friday report in USA Today, since the end of September, the top six markets were Tampa, Orlando, Miami, Philadelphia, Phoenix, and Harrisburg. 

Florida -- a perennial swing state enmeshed in a tight contest -- is crucial, with the belt from Tampa to Orlando holding voters from key demographics: the elderly, suburban women, Latinos and military service members.

Early voting begins in Florida on Oct. 19 as other states across the country see impressive early turnout.

This year is expected to be a record-setting one for campaign spending, and residents of the Sunshine State are seeing the fruits of that in a bumper crop of political spots.
