Rick Santorum on Friday was glitter bombed by a male activist, the AP reported.

“Stop the hate!” the unnamed activist yelled. “Taste the rainbow!” (The video is embedded in the right panel of this page. Visit our video library for more videos.)

The incident occurred as Santorum arrived at his final campaign event in Johnston, Iowa. Polls show Santorum surging just days before the Iowa caucuses are set to take place.

Santorum joins GOP rivals Newt Gingrich and Michele Bachmann in being showered with glitter at a public event. Former Minnesota Governor Tim Pawlenty was also glitter bombed but has since dropped out of the race.

Previous incidents have been linked to gay rights.

Activist Rachel E. B. Lang's glittering of Bachmann during a stop in Minneapolis was a direct protest against her support for a proposed constitutional amendment that would ban gay marriage in the state. “Keep your hate out of our constitution!” Lang yelled.

Gingrich was hit with glitter during a book signing event in Minneapolis.

“Feel the rainbow,” activist Nick Espinosa yelled as he doused Gingrich with glitter. “Stop the hate. Stop the anti-gay politics. It's dividing our country and it's not fixing our country.”
