Peters has consistently posted $1 million quarters since he got into the race. Former Michigan Secretary of State Terri Lynn Land (R) matched his $1 million quarter and added $600,000 from her own pocket, part of the $5 million she's promised to spend in the race.

Neither candidate has announced how much cash on hand they have. As of the end of September, Peters had $2.5 million in the bank while Land had $1.9 million.

"The overwhelming support from Michiganders hailing from all 83 counties shows that Gary is the only candidate earning the trust of middle class families and small businesses, and he is a proven independent voice for Michigan," Peters for Michigan Campaign Manager Julie Petrick said in a statement to The Hill.

Republicans are increasingly bullish about their chances in Michigan, where Sen. Carl Levin (D-Mich.) is retiring. Democrats believe they still have the edge, but Land's ability to self-fund is making some nervous.
