KANSAS CITY, Mo. (Reuters) - Two weeks before a tight U.S. presidential election, tension among bitterly divided voters is translating into a barrage of attacks on political targets that can't talk back - yard signs. [snip] "I was outraged," said Lis Ross of Fairway, Kansas, whose "Kansans for Kerry" sign disappeared last week. "What made it worse was that they replaced it with a Bush-Cheney sign. I ran out there and ripped it into little pieces." [snip] In Ohio, two men were reportedly caught on videotape urinating on a Bush-Cheney sign, and in Madison, Wisconsin, someone burned a swastika into a lawn with a Bush sign. Some people are working overtime to protect their signs. Mark Shemet of Jaffrey, New Hampshire, has had to replace two stolen Kerry signs in the last week alone. Pennsylvania Democrats have threatened to spread itching powder on signs to keep the opposition at bay, and an Illinois family last week covered their yard sign with petroleum jelly to repel thieves.
