Michigan Lt. Gov. Dick Posthumus (R) made pit stops in three Great Lakes cities on Monday to spread the word that he doesn’t support the plan by his boss, Gov. John Engler (R), to end a moratorium on new leases for oil and gas drilling under the lakes. Engler says the drilling would be environmentally a-okay; Posthumus says the risks would be too great. Why the split? You guessed it: Posthumus is expected to run for governor next year to succeed the term-limited Engler. All five Democratic gubernatorial candidates have already spoken out against Engler’s plan.
