Washington (CNN) - Ohio Gov. Ted Strickland said Friday that his security has been "beefed up" in recent days after a domestic extremist group sent letters to more than 30 governors demanding that they resign.
Nevertheless, in an interview on CNN's "John King USA," Strickland said he does not feel "personally threatened."
Federal intelligence officials said there do not appear to be credible or immediate threats of violence attached to the letters.
"But I do think it's sad that in our nation today we would have these kinds of threats," Strickland said.
"You never know when some wrong-thinking person or some hate-filled group will carry out actions that could be harmful to individuals. I hope it doesn't happen anywhere across our nation, but I can tell you that I feel very secure here in Ohio."
Strickland is seeking a second term this November, but as a Democrat in a swing state struggling under the weight of a tough economy, his re-election is hardly assured. His Republican opponent is former Rep. John Kasich.
Strickland was optimistic about the economy, though, telling King it has "bottomed out."
"I believe we are on the way to recovery," he said. "I also believe this is going to take us some time. I don't think the recovery will be a rapid recovery. But I hope it's steady and consistent going forward."
Strickland said he is "very confident" he will be re-elected. Though many Republicans are comparing this midterm election to the 1994 GOP landslide, the governor said he sees a distinction. In 1994, he argued, contentious measures like President Clinton's crime bill were enacted too close to election day for voters to understand their impact.
"I think what's happened this election cycle has happened early enough, and I am talking specifically about the passage of the health care bill, that there is sufficient time for the electorate to come to understand that that was a good vote on the part of the Democrats and that the health bill will be beneficial to them."
Strickland invited Kasich to appear on the show with him next time, saying it would be "a joy."
