MILWAUKEE (AP) — Former President Barack Obama has appearances in Wisconsin and Michigan on Friday aimed at boosting turnout to aid Democrats, including black voters.

Low turnout in Milwaukee by African-Americans proved costly for Hillary Clinton in 2016 when she narrowly lost Wisconsin. One analysis found turnout fell nearly 20 points compared to Obama’s 2012 run.
