Former Michigan Gov. William Milliken doesn't recognize the John McCain he's known before:
"He is not the McCain I endorsed," said Milliken, reached at his Traverse City home Thursday. "He keeps saying, 'Who is Barack Obama?' I would ask the question, 'Who is John McCain?' because his campaign has become rather disappointing to me.
"I'm disappointed in the tenor and the personal attacks on the part of the McCain campaign, when he ought to be talking about the issues."
Milliken, a lifelong Republican, is among some past leaders from the party's moderate wing voicing reservations and, in some cases, opposition to McCain's candidacy.
