I used to know a family that moved from MI to NJ in the late 80's. I went to school with one of the kids in the family at that time before they moved to a neighboring town in NJ. Now I know why they moved from MI to NJ: because of Blanchards tax hike I guess and high property taxes. Keep in mind the public sector unions were not as big then in NJ as they are now.
How did Blanchard get 68% in 1986 after that big of a tax hike anyway? NJ dumped Florio in 1993 because of a tax hike.
His GOP opponent, William Lucas, was Black (and anti-abortion). Lucas was only the second Black major party nominee for Governor (the first was Tom Bradley, D-CA, in 1982). Blanchard overwhelmingly defeated Lucas, 68.1% - 31.4%. Blanchard carried Macomb (which had just voted 2-1 Reagan and narrowly voted for Jack Lousma (R) over Carl Levin for Senate in 1984) 68.0-31.5. Blanchard also carried normally Republican Allegan, Hillsdale, Missaukee, Lapeer, Livingston, and Sanilac Counties. The only county Lucas won was Ottawa, a bastion of GOP and Christian Reformed Church loyalty, which Lucas won 55-45.
BTW, in 1974, Milliken (R) won with 1,356,865 votes (51.07%) to Levin's 1,242,247 (46.75%).
