Congress totals, participation, party alignment & sources

Recorded entries: 676
Recorded “not voting”: 19

Recorded “not voting” accounts for 2.8% of this member’s 676 recorded entries in the 119th Congress. Review “not voting” entries.

Counts and this share cover the selected Congress before all filters. The share is “not voting” entries divided by recorded entries, rounded to one decimal place. This is not an attendance rate: missing entries are not counted, and voting eligibility varies by office and service period. “Not voting” is the source’s label; it gives no reason for nonparticipation. Recorded entries also include yes/no, present and named choices.

Party alignment over time

Compare current members across a chamber →

How often this member voted with their party when Democratic and Republican majorities took opposite sides. Each roll call has equal weight. This describes voting behavior, not cooperation or ideology.

Showing all vote types in both Congresses, before text, choice, or alignment filters. Compare the same chamber and party; the agendas, service periods, and number of votes differ. The 119th Congress is still in progress.

Vote coverage & sources

Official recorded floor roll calls in the selected Congress. Voice votes, unanimous consent and committee votes are excluded. Only entries explicitly listing this member are included; missing entries are not missed votes. Retrieval dates describe source inventory checks; individual roll-call records may be retained from earlier captures.

Delegates and the resident commissioner do not vote on final House floor passage. A member who had not yet taken office, had left office, or was not eligible is not assigned a missed vote. Zero entries can reflect no eligible service.

No covered records; no spending total established.

Coordinated party spending

No covered records; no spending total established.

Subtotals sum covered non-memo records, including signed corrections. Rapid notices and electioneering disclosures have no aggregate because they can overlap other records or mention multiple candidates. Spending supporting this person is distinct from spending opposing an opponent, which appears on the opponent’s profile when covered.

Independent spending — rapid notices

24- and 48-hour notices provide earlier visibility. They can appear again in regular reports, so no notice total is calculated and these amounts are never added to regular-report subtotals.
