After retiring from public office, Milliken moved back to Traverse City. He soon joined the board of directors of the
Chrysler Corporation and chaired the Center for the Great Lakes, a research center dedicated to the protection of the
Great Lakes. He spoke at the funeral of former
Mayor of Detroit Coleman Young in 1997, who was the first African American elected as mayor of that city. In presidential elections since 2004, Milliken expressed support for several Democratic candidates. In
2004, he endorsed Democratic senator
John Kerry in his bid to unseat
George W. Bush, stating "The truth is that President George W. Bush does not speak for me or for many other moderate Republicans on a very broad cross section of issues." In
2008, he endorsed Republican
John McCain, but backed away in October after McCain's campaign began attacking Democratic candidate
Barack Obama. He told
The Grand Rapids Press that "He is not the John McCain I endorsed." Milliken expressed concern about the direction of the Republican Party: "Increasingly, the party is moving toward rigidity, and I don't like that. I think
Gerald Ford would hold generally the same view I'm holding on the direction of the Republican Party." In August 2016, Milliken announced that he would vote for
Hillary Clinton for president in the
2016 presidential election, saying that
Donald Trump does not embody Republican ideals. In Michigan state elections, Milliken supported candidates from both parties. In
2010, he endorsed businessman
Rick Snyder in the Republican gubernatorial primary, and continued to support him in the general election. In
2014, he endorsed Snyder for a second term. In the
2014 Senate election, he supported Democrat
Gary Peters over the Republican nominee
Terri Lynn Land. In 2015, Milliken signed an
amicus brief in support of same-sex marriage. == Death ==
