Barr, the 2008 Libertarian Party presidential nominee, told FOXNews.com that he's taking steps to get his name removed from the report, which he said could actually "dilute the effectiveness" of law enforcement agencies.
"It can subject people to unwarranted and inappropriate monitoring by the government," he said. "If I were the governor of Missouri, I'd be concerned that law enforcement agencies are wasting their time and effort on such nonsense."
Barr said his office has received "several dozen" complaints related to the report.
Mary Starrett, communications director for the Constitution Party, said Baldwin, the party's 2008 presidential candidate, was "outraged" that his name was included in the report.
"We were so astounded by it we couldn't believe it was real," Starrett told FOXNews.com. "It's painting such a large number of people with a broad brush in a dangerous light."
Michael German, national security policy counsel for the American Civil Liberties Union, said the report "crosses the line" and shows a disregard for civil liberties.
"It seems to implicate people who are engaging in First Amendment protected activities and suggest that something as innocuous as supporting a political candidate for office would mean that you're harboring some ill-intent," German told FOXNews.com. "It's completely inappropriate."
German � who claims the number of fusion centers nationwide is closer to 70 � said the centers present several troubling concerns, including their excessive secrecy, ambiguous lines of authority, the use of data mining and military participation
