Michigan GOP leader signals Senate bid, sets up clash with Trump-endorsed Mike Rogers

Former Michigan GOP co-chair Bernadette Smith has filed paperwork with the Federal Election Commission signaling a likely Senate run, setting up a potential longshot Republican challenge to Trump-backed former Rep. Mike Rogers for the party's nomination in the battleground state’s open Senate seat.If Smith, who resigned from her co-chair position with the state party last week, moves forward and formally declares her candidacy, she would join a GOP primary field that already includes Rogers, who has been endorsed not only by President Donald Trump, but also by Senate Majority Leader John Thune
