Is Obama asking Missouri Law Enforcement to go after those who "lie" during the campaign

Is this serious? KMOV has the story about St. Louis prosecutors who are promising to bring criminal charges against people that tell lies about Obama.

UPDATE; Missouri Governor Matt Blunt responds:

“St. Louis County Circuit Attorney Bob McCulloch, St. Louis City Circuit Attorney Jennifer Joyce, Jefferson County Sheriff Glenn Boyer, and Obama and the leader of his Missouri campaign Senator Claire McCaskill have attached the stench of police state tactics to the Obama-Biden campaign.
“What Senator Obama and his helpers are doing is scandalous beyond words, the party that claims to be the party of Thomas Jefferson is abusing the justice system and offices of public trust to silence political criticism with threats of prosecution and criminal punishment.
“This abuse of the law for intimidation insults the most sacred principles and ideals of Jefferson. I can think of nothing more offensive to Jefferson’s thinking than using the power of the state to deprive Americans of their civil rights. The only conceivable purpose of Messrs. McCulloch, Obama and the others is to frighten people away from expressing themselves, to chill free and open debate, to suppress support and donations to conservative organizations targeted by this anti-civil rights, to strangle criticism of Mr. Obama, to suppress ads about his support of higher taxes, and to choke out criticism on television, radio, the Internet, blogs, e-mail and daily conversation about the election.
“Barack Obama needs to grow up. Leftist blogs and others in the press constantly say false things about me and my family. Usually, we ignore false and scurrilous accusations because the purveyors have no credibility. When necessary, we refute them. Enlisting Missouri law enforcement to intimidate people and kill free debate is reminiscent of the Sedition Acts - not a free society.”
