Pointing to a video of Tammy Baldwin dancing at a Gay Pride event, the Tommy Thompson campaign has questioned her values.

Baldwin and her GOP rival Thompson, the former governor of Wisconsin, are competing to capture the seat being vacated by Wisconsin Senator Herb Kohl. If elected, Baldwin, 50, would become the first openly gay U.S. senator.

Brian Nemoir, Thompson's political director, sent an e-mail and posted a Twitter message on Thursday concerning Baldwin at a 2010 Gay Pride event, ahead of her prime time speech at the Democratic National Convention.

Referring to Baldwin's assertion that her speech would focus on “heartland values,” Nemoir wrote, “Clearly, there's no one better positioned to talk 'heartland values' than Tammy.”

The attached video shows Baldwin dancing on stage with the disco band VO5 as it plays the theme from Wonder Woman. Baldwin hugs the group's frontwoman, who is appropriately dressed as the comic book heroine. (The video is embedded on this page. Visit our video library for more videos.)

Nemoir acknowledged sending the e-mail in an interview with WisPolitic.com.

“I think there are issues in this race that are extremely significant that will be generated on a day-to-day basis and I look forward to coverage of those issues,” he said.
