Donald Trump’s presidential campaign “has spent $1.8 million on polling from June 2015 through September of this year (the most recent month for which data are available.) The report also lists $3.2 million spent on hats,” the Washington Post reports.

“Trump has probably spent more on hats than he has spent on direct mail. The campaign filings occasionally aggregate a few things from the same vendor under one line-item, so some of the hat spending was on collateral generally that includes some hats. (His campaign spent more than $2 million on a line-item that was exclusively hats, though.) Overall, Trump’s spent about $15.3 million on collateral — shirts, hats, signs, etc. — more than he has spent on field consulting and voter lists and data.”
