Earlier this year, Ashley Todd, the disturbed young woman who made up a fake story of being attacked by a black man enraged by her John McCain sticker, was working for the Ron Paul campaign.

In March, Ms. Todd was asked to leave a grass-roots group of Ron Paul supporters in Brazos County, Texas, group leader Dustan Costine said. He said Ms. Todd posed as a supporter of former Arkansas governor and presidential candidate Mike Huckabee and called the local Republican committee seeking information about its campaign strategies.

“She would call the opposing campaign and pretend she was on their campaign to get information,” Mr. Costine said last night. “We had to remove her because of the tactics she displayed. After that we had nothing to do with her.”

About a month earlier, he said, Ms. Todd sent an e-mail to the Ron Paul group saying her tires were slashed and that campaign paraphernalia had been stolen from her car because she supported Mr. Paul.
