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.
