TAMPA, Florida (AP) - A man apparently enraged by a campaign sticker for President George W. Bush on a woman's sport utility vehicle chased her for several kilometres and tried to run her off the road while holding up an anti-Bush sign, police said. "He told our officers that he just got mad at her, so he went after her," said police spokesman Joe Durkin. Nathan Winkler, 31, was freed on $2,000 US bail early Wednesday on a charge of aggravated stalking, which carries up to five years in prison. No one answered the telephone Thursday at Winkler's home, but his father, John Winkler, said: "I know that he's very anti-Bush. But I don't see him doing anything like that. He's the least aggressive person I know." Winkler told police he got upset with the woman, 35-year-old Michelle Fernandez, after she made an obscene gesture, Durkin said. Fernandez was taking her 10-year-old son and three-year-old daughter to a ball field Tuesday when the incident occurred. "Whatever gestures I made, I made them because I was trying to figure out why he was honking at me and pointing at his sign," Fernandez said. Police said that as Winkler chased the woman's vehicle, he held up a small sign that read: "Never forget Bush's illegal war murdered thousands in Iraq." Fernandez found a police officer and described the car and licence number. Within an hour, police arrested Winkler at his home. Fernandez said she is a registered Democrat who voted for Bush in 2004.
