It also became the most notable proxy battle between the Democratic Party’s establishment and progressive wings.Candidates from the left-flank – including democratic socialists – have found surprising success in the party’s US House primaries, including in New York and Denver, in areas that tend to veer farther left. A progressive victory in Michigan would be significant for the movement.The winner of Tuesday’s race will face the Republican nominee, former representative Mike Rogers, in November, to succeed the retiring Democratic senator Gary Peters. Rogers ran unopposed in the Republican primary.In other developments:
