Track record

Assembled from Congress.gov · FEC · official disclosures — each fact links its own source

These are verifiable facts from the public record, assembled in one place and presented without judgment. They are not a score, a grade, or a ranking. Context matters: a missed vote may be excused, on leadership or committee duty, or paired; a party-unity rate reflects agenda alignment, not virtue or independence; a disclosed trade or a documented relationship is a required public filing, not evidence of wrongdoing. Each fact links to its full source below.

    Roll-call participation →

    voted in 17 recorded roll calls

    Missing a vote is not inherently negative — an absence can be excused, reflect leadership or committee duty, or a recorded pairing.

  • 31
    Bills sponsored →

    plus 399 cosponsored

    A count of bills introduced as the primary sponsor; most legislation never advances, regardless of who sponsors it.

  • 0
    Sponsored bills enacted →

    of 31 bills sponsored

    Whether a bill becomes law depends on the whole Congress, not the sponsor alone; substantive provisions often pass folded into other vehicles.

  • 100%
    Party-unity voting

    votes with the party majority · on 8 party-line votes

    Party-unity is how often a member votes with their own party's majority on party-line votes — it reflects agenda alignment, not loyalty, independence, or virtue.

  • 0%
    Cross-party voting

    votes with the other party's majority on those same votes

    The share of the same party-line votes cast with the OTHER party's majority — a descriptive rate, not a measure of principle.

    Documented positions →

    no positions documented yet

    Documented, sourced positions we have on record — the absence of a documented position is not the absence of a view.

    Committee assignments →

    committees and subcommittees

    Committee seats are assignments made by party leadership — a measure of role and jurisdiction, not an achievement or a conflict in itself.
