Republican presidential contender Mitt Romney is finding himself increasingly under “attack” from glitter bomb protest acts, which have mainly been the domain of gay rights activists targeting Republican politicians and other public figures who oppose same-sex marriage.

And now Peter Smith, 20, a Colorado student is facing misdemeanor charges after flinging glitter toward Romney to protest against his “general political philosophy,” and not only his stance on gay marriage, writes Keith Coffman at Reuters.

Romney was shaking hands with supporters in an auditorium when the glitter was thrown at him. As Secret Service agents ushered him away, Smith was escorted out by other agents and local authorities.

Denver Police spokesman Sonny Jackson said that the Denver authorities detained Smith overnight, and is set to be charged with creating a disturbance, throwing a missile and an unlawful act on school property.

The charges come with the potential of six months in jail and a $1,000 fine.

Smith says he has no regrets about his protest.

Other candidates like Newt Gingrich, Rick Santorum and Ron Paul have also been targeted with glitter bombs.

When former Republican candidate Tim Pawlenty was struck with glitter in June 2011, former Arkansas Governor Mike Huckabee said that “people ought to be arrested” for throwing glitter, which he called “an assault,” writes Coffman.

“You’ve got to draw the line,” Huckabee said.

A spokesman refused to confirm or deny if the Secret Service sees glitter bombing as a pressing problem.

“We want to make sure everything is a safe and secure environment,” they said.

However, Smith said that agents were lenient.

“They just mentioned this act was an issue that they’ve been trying to deal with more and more,” he said.
