The race for Michigan's open Senate seat between Democratic U.S. Rep. Elissa Slotkin and Republican former congressman Mike Rogers remained too early to call Wednesday after results in other states showed Democrats lost their slim majority in the upper chamber.

Democrat Elissa Slotkin has won Michigan's high-stakes race for US Senate, according to final vote tallies released Wednesday afternoon more than 15 hours after polls had closed.

Representative Elissa Slotkin, a centrist with strong national security credentials, won the contest to succeed the retiring Senator Debbie Stabenow.
