LOS ANGELES — Several billboards scattered around Los Angeles look at first glance like ads for Bernie Sanders' presidential campaign, but they actually ask, "Feel the Burn?"

The ad campaign is the work of the AIDS Healthcare Foundation, which is urging anyone who might feel painful symptoms of sexually transmitted diseases to get free screenings.

The billboards use the same style as Sanders' campaign, which has adopted the slogan "Feel the Bern" — itself a play on the fitness workout catchphrase.

Both the senator and the foundation use white letters underlined by red and white swooshes against a blue background.

AIDS Healthcare spokesman Jason Farmer says in a press release that Sanders is getting through to young people and the organization hopes its message does, too.
