The McCain campaign this evening sent out a press release that former Michigan governor William Milliken – a close ally of the late George Romney – has endorsed John McCain for president. From the release:

“I have long admired Senator McCain for his straight talk and service to the country,” said Governor Milliken. “There’s a real sense of integrity in the firm positions he takes, even though they are not always popular. I don’t agree with him on all issues, but I like his well-earned reputation of saying what he means, and meaning what he says.”
John McCain thanked Governor Milliken for his support, stating, “Governor Milliken is among the most honorable and decent people to serve the great state of Michigan. I admire his service and am grateful for his support.”
William G. Milliken served as Michigan’s 44th and longest-serving governor from 1969 to 1982. From 1963 to 1969, Milliken served as Lieutenant Governor under Governor George Romney.

The Milliken/Romney dynamic – including the fact that Milliken endorsed John Kerry in 2004 – was explained in David Broder’s column this morning.
