An election threat scribbled on the bathroom wall of a Jacksonville, FL, high school vows violence if Barack Obama is elected president.

The threat unnerved teachers and parents – one mother so much so that she pulled her child out of school.

The words: "If Obama is elected as president, the new KKK is going to blow up the school," were written on the wall at First Coast High School, WJXT in Jacksonville reported.

"I take it seriously, especially with the high school right here with all the kids it’s just going to be chaos," said parent Sherry Hyatt, who said the message is just the most recent in a string of problems at the school – so she pulled her son out.

"There’s a hit list going around, kids being stabbed, I mean the drugs coming on to school grounds. All of that kind of stuff. I’m through with it," added parent Nichelle Maddox.

Jacksonville police are investigating whether the message is a legitimate threat. The school-board spokeswoman said the safety of its students is taken seriously, but the board doesn’t believe students are in danger.

The news comes after bigger news this week that the federal Bureau of Alcohol, Tobacco, Firearms and Explosives thwarted a neo-Nazi skinhead plot for a killing spree that targeted 102 black people and Obama.

The men being accused of the plot are Daniel Cowart, 20, of Bells, TN, and Paul Schlesselman, 18, of West Helena, AR. They were officially charged in a federal complaint, Friday, October 24. The complaint charges the two with the illegal possession of a sawed-off shotgun, conspiracy to rob a federal firearms dealer and making threats against a major candidate for the office of president.

"The United States Secret Service takes all threats against presidential candidates seriously and is actively investigating the allegations," said Richard Harlow, special agent in charge of the Secret Service-Memphis, TN, field office.

Obama himself said this week that he’s not worried about threats to his life as he tries to become the first black U.S. president, saying that hate groups have been marginalized by his candidacy.

"I think what’s been striking about this campaign is the degree to which these kinds of hate groups have been marginalized. That’s not who America is. That’s not what our future is," Obama told Pennsylvania TV station KDKA.

Asked if he was concerned about his safety, Obama said no.

"I’ve got the best folks in the world — the Secret Service," he said.

ABC News reports that federal law enforcement sources say Obama has been the target of well over 500 threats, most of which are not taken seriously. But in about a dozen or so cases, the threat was considered serious enough that law-enforcement agents were assigned to track down suspects. Threats of violence, harsh invective, language such as "get rid of" or "kill" or "eliminate" are all considered triggers for possible investigation.
