'It's non-stop': Swing state voters bombarded with ads - will they make a difference?

Like many Americans, Hayden Cook decided long ago who to vote for in this year's presidential election.

And yet, every day, the 19-year-old from Wilkes-Barre, Pennsylvania is bombarded with political ads, despite installing a blocker on YouTube and opting out of cable television.

"It's still so constant," Cook said. "Work is six minutes away - you're already hearing two or three ads; then we have the radio on at work and there's ads there."

More than $10bn (£7.6bn) is expected to be spent on political advertising this election. That is up some 20-25% from 2020 - itself a record-setting cycle - depending on which forecaster is consulted.
