Gov. Gretchen Whitmer raised $3.1 million over three months for her reelection campaign and had $12.6 million on hand a year before the 2022 election.
Former Detroit police chief James Craig outraised a field of Republicans vying to challenge her, collecting $1.4 million.
The numbers were reported Monday, the quarterly deadline.
The Democratic governor continued to use an exemption to collect more than the individual $7,150 limit because of longshot efforts to recall her from office.
The GOP is challenging the strategy in court. Eleven Republicans have formed candidate committees to run against or explore a challenge to Whitmer.
