Messmer co-sponsored Indiana SB200 (2022), which would have provided driving cards to undocumented immigrants in Indiana. The bill stated: 'An individual who is an Indiana resident and cannot provide proof of identity and lawful status in the United States may apply for a driving card learner's permit and driving card to obtain driving privileges.' He also co-authored Indiana SB135, which would allow undocumented immigrants to pay in-state college tuition rates.

As an Indiana state senator (2022), Messmer co-sponsored legislation providing driving cards and in-state tuition rates to undocumented immigrants — pragmatic accommodation measures backed by the Indiana Chamber of Commerce and law enforcement. In his 2024 congressional campaign, he rebranded as an immigration hardliner, advocating for deportations, ending birthright citizenship, and securing the border. A GOP primary opponent's ad attacked him: 'Mark Messmer co-sponsored a bill to allow illegal immigrants to apply for driver's licenses and in-state tuition for colleges in Indiana. Now he wants to represent us in Congress?'

His district has a 13.4% poverty rate, higher than the national average, meaning the Medicaid cuts he voted for disproportionately harm his own constituents.

Scoring Methodology

The Capture Risk Score is a composite 0–100 index measuring potential regulatory capture of elected officials. It is computed from seven weighted components:

ComponentWeightSignal
Contradiction Risk30%Stated positions contradicted by the record (recent findings boosted)
Donor Influence20%Distinct documented donors (FEC Schedule A PACs); inferred donors do not count
Connection Density20%Mapped relationships to lobbyists, contractors, interest groups; donor links excluded
Silence Risk15%Topics where donors have interests but the official is silent
Intelligence Volume15%Documented facts from verified sources
Constituency Deviation0%Shown, not weighted — a model estimate, not a record
Voting Misalignment0%Shown, not weighted — needs platform commitments almost nobody has; the roll-call record on /votes is the vote signal

Each component is the member's standing among all scored members of Congress, and the weighted sum is the overall score. Tiers are ranks: Critical is the top 5%, High the next 10%, Elevated the next 20%, Moderate the next 30%, and Low the rest.

Officials without at least 2 documented facts, 1 contradiction analysis, 1 voting record, or 1 constituency baseline are marked Insufficient Evidence and excluded from numeric ranking.

Contradiction findings from the last 180 days receive a recency boost. High-severity contradictions (score ≥ 70) receive additional weight.

Calculation Methodology

Contract values are summed from documented money flow chains where this entity appears as a source or destination node. Amounts are drawn from USASpending.gov, FEC filings, SEC EDGAR, or LD-2 lobbying registrations.

Donor contributions aggregate documented amounts from the donor_interests table, sourced from FEC individual and PAC contribution filings.

Connected officials are elected officials in our database with a mapped relationship (lobbying, board membership, campaign contribution, etc.) to this entity.

Annualised flow represents the total documented dollar amount traced through money flow hops involving this entity. Where hop-level amounts are unavailable, the chain-level documented total is used as a conservative upper bound.

All figures are drawn from public filings. Estimates are conservative — undisclosed transactions, dark money, and vanish-point hops are excluded from totals. This is a minimum documented floor, not a ceiling.
