Business executive Lisa McClain has defeated two other Republicans to win the open primary in Michigan’s 10th Congressional District.
Second-term Rep. Paul Mitchell is retiring from the seat that includes the Thumb region and much of Macomb County north of Detroit.
McClain will be favored to win the Republican-leaning district in November.
She will go against environmental activist Kimberly Bizon, who won the Democratic primary.
McClain defeated state Rep. Shane Hernandez and retired military leader Doug Slocum in the GOP contest.
