— J Street, the Joint Action Committee for Political Affairs and Emgage Action
Arguments against
The Republican National Committee's research operation circulated a clip in June 2026 of her repeatedly swearing while defending her record on Cuba and Venezuela, which Republicans used to argue she reacts badly to scrutiny of her voting record.
— RNC Research, reported by the Daily Caller
What we couldn’t verify
The clip was distributed by a party research operation and reported by an openly conservative outlet; Dingell's own account of the exchange was not located.
No criticism of her by name from Heather Smiley's campaign or from the National Republican Congressional Committee was located.
Her 2026 fundraising was not established from sources read.
LGBTQ inclusion within the Republican Party; she is endorsed by the Log Cabin Republicans.
What they’ve actually done

Endorsed by the Log Cabin Republicans.
Has not held elected office.
Arguments in favor
We found none published about this candidate in the sources reviewed.
Arguments against
We found none published about this candidate in the sources reviewed.
What we couldn’t verify
Smiley's biography and most of her policy positions could not be established: no campaign website, candidate questionnaire or news profile covering her was located beyond the primary result. The standsFor list is limited to what her single reported endorsement indicates.
No published criticism of Smiley by name could be found. Searched: her name with 'criticism', against Democratic Congressional Campaign Committee material, against Debbie Dingell's campaign, and against Michigan Daily, Michigan Advance and Detroit News coverage.
Her fundraising was not established from sources read; the district voted Democratic by more than twenty points in 2024.

Michigan held its primary on August 4, 2026. Democratic incumbent Debbie Dingell and Republican Heather Smiley both secured their nominations unopposed, according to the Michigan Daily; some listings also name Jason Cloutier, who filed as a Democrat, and that discrepancy could not be resolved from sources read. The district covers Ann Arbor and Washtenaw County plus parts of western and southern Wayne County. Roster confirmed against Ballotpedia and the Michigan Daily. Criticism of Smiley by name could not be found, so her entry carries no arguments in either column.
This is one contest on a longer ballot
A Michigan ballot also carries state legislative districts, county offices, judicial seats and often local questions — and which of them you vote on is decided by your street address, not your city or ZIP code.
