LANSING, Mich. (AP) — A top Republican lawmaker’s proposal that would increase Michigan’s hourly minimum wage to $8.15 in September could thwart a current ballot drive to gradually raise it to $10.10 by 2017.

Senate Majority Leader Randy Richardville introduced the bill Thursday, about three weeks before the deadline for backers of the higher wage hike to file signatures to put their initiated law before the GOP-led Legislature. Assuming legislators do nothing, the outside measure would head to a statewide vote in November.
