Another one crosses over:

The first Republican woman State Senator in Wisconsin history announced on Tuesday that she would be supporting Barack Obama, in part because of the negative tone of the McCain-Palin campaign and, specifically, the use of "dishonorable" anti-Obama robocalls.

"All of us should be extremely wary of the half truths and outright untruths that have been spread by the recent negative campaigning and shameful automated phone calls," said Barbara Lorman of Fort Atkinson. "While my admiration for Senator Obama has grown with his positive approach to addressing the challenges facing our nation, my disappointment with the McCain campaigned has deepened. The negative tactics are inappropriate, downright dishonorable and have no place in the State of Wisconsin."

The fact that she is a lifelong Republican -- she left the Senate in 1994 and, until recently, was the longest woman serving senator in Wisconsin history -- now crossing party lines is also of interest.

"I'm a lifelong Republican, but Senator Obama is the right leader for our country and will deliver the change we need," Lorman said in a statement released by the state's Democratic Party. "After taking a careful look at the qualities of both McCain and Obama and who would be best for our country, I found that Senator Obama's ability to bridge the partisan divide to work toward solid solutions that will get our nation back on the right track meant he is the right choice this November."
