by Violet Ikonomova Detroit voters this year have a chance to tip the balance of power on City Council, with four of nine seats up for grabs on a body that typically votes with Mayor Mike Duggan. Nearly two dozen council candidates will appear on the primary and November ballots. Primaries will be held in Districts 1, 4, 7 and for two at-large, or citywide, seats. There will be no primary in Districts 2 and 6, where the two candidates in each race will automatically advance to the November ballot. District 5 Councilmember Mary Sheffield and District 3 Councilmember Scott Benson are meanwhile running for re-election unopposed.
