§2Who they are
Why this matters: Background and experience help you judge how someone might do the job. These come from public records and the candidate's own materials.
Drafted by AI from the public sources cited. Each sentence links to its source.

Why they say they're running

§3What they've said on the issues
Why this matters: These are positions the candidate has stated publicly — on their campaign website or in public statements — summarized in plain words with a link to where they said it. Issues they haven't spoken about publicly are left out.
Drafted by AI from the public sources cited. Each sentence links to its source.
Each issue has its own range of views. A position is marked on that range only when the candidate's own statement clearly matches one option; there is no overall left–right score.
Crime, Policing and Prisons
His campaign website says he would work with law enforcement to give officers the support and funding they need.4
Immigration
His campaign website says America is enriched by immigrants, describes the roughly 1.2 million people admitted legally each year as vetted to be nonviolent, self-reliant and willing to assimilate, and says those not admitted should build liberty in their own countries.4
§4Money
Why this matters: Campaigns report where their money comes from and how much they have left. Outside groups that spend on their own, without coordinating with the campaign, report that too.
Reported to the Federal Election Commission for the 2025–2026 election cycle, through October 14, 2026.5

§5Financial disclosures
Why this matters: Federal candidates and members of Congress must report their assets, income, debts and outside jobs, and members must report stock trades. These filings show possible conflicts of interest.
Senate candidates and senators file with the Senate's own disclosure system, which asks each visitor to agree to its terms before searching, so we can't link straight to a filing. You can search for Mark Baisley at efdsearch.senate.gov6.
