Trump and Clinton use merchandise to wage attacks on each other

Presidential rivals Donald Trump and Hillary Clinton are not just using speeches and television ads to attack their opponent. They've even started attacking each other on their campaign merchandise.

Each candidate has taken their opponent's trademark look and turned it against them.

Hillaryclinton.com features a red baseball cap similar to Trump's "Make America Great Again" hat that features the words "I have a good brain."

Donaldjtrump.com is selling a shirt that shows a pantsuit with jail stripes and the words "Crooked Hillary" in the bottom left corner.
