As an avid supporter of Hillary Rodham Clinton in the Democratic primaries, Debra Bartoshevich is not alone in her frustration over Clinton's defeat.

She's not alone in refusing to support Barack Obama.

And she's not entirely alone in saying she'll vote this fall for Republican John McCain instead.

But what makes her unusual is that she holds these views as an elected delegate to the Democratic National Convention in Denver this summer.

"I'm sure people are going to be upset with me," said Bartoshevich, a 41-year-old emergency room nurse from Waterford in Racine County, and convention delegate pledged to Clinton.

Joe Wineke, chairman of the Democratic Party of Wisconsin, reacted with disbelief when first told Friday afternoon that one of his state party delegates is now a McCain supporter.

"Not a delegate? To the national convention?" said Wineke, who was getting ready for the start of the Wisconsin state party convention Friday in Stevens Point.

"We have a Clinton national (convention) delegate who says she's voting for John McCain?" Wineke repeated, for clarification. "I've never heard of such a thing."

Wineke said "almost everybody I know who was for Hillary" is solidly behind Obama now. As for Bartoshevich, he said, "my suspicion is she doesn't know what she's getting into" because "the delegates to this convention will be very upset."

Asked if publicly supporting the other party's presidential nominee could affect a delegate's convention status, Wineke said, "I never thought I'd ever get a question like this."
