This is the third in our four-part series on the 2018 campaign ads, and this week’s theme, in honor of Halloween, is fear. Dum-dum-dum!

Candidates have always sought to make voters afraid of all kinds of things (we have a few colorful historical fear ads in the video), but this year the main fear is foreign threats. As you might imagine, most of it is coming from Republicans, but there are some fear-inducing ads from Democrats, too. Enjoy.
