Dorothy Peterson, wife of former Republican Governor Walter Peterson, has endorsed Barack Obama.

During the New Hampshire primary Walter Peterson served as honorary chairman of John McCain's campaign and is also chairman of Republicans for Lynch, a group that has endorsed Gov. John Lynch (D-Hopkinton).

"I believe Senator Obama is the best prepared to lead this country at a time when we are in desperate need of strong leadership on everything from women's rights to the war in Iraq," Dorothy Peterson said in a press release. "I am extremely worried that with the wrong choice this fall, Roe v Wade could be overturned and our government could take away a woman's right to make what is a very personal decision about when and how to raise a family."
