Kid Rock's chances of winning Michigan are slim to none. Michigan isn't a Republican state, nor even a particularly purple state. Voter turnout was down in 2016, especially among African Americans, in Michigan, but also among low-income White voters who opted to abstain or vote third party instead of vote for Clinton. In 2012, Stabenow defeated a bigoted GOP rival quite decisively. Kid Rock is just a joke.
But maybe Trump can campaign for him. You know, do a tour through Michigan, maybe rock out together about "bad hombres" and grabbing women by the pu**y.
Of course there are excuses for Hillary losing.
