Against both parties counts votes where the Democratic and Republican majorities took the same side and the member voted the other way. With winning side counts votes that matched the final outcome. A close vote is a roll call decided by 5 votes or fewer; absences can have many causes. Agreement is the share of votes both members cast on which they voted the same way (at least 100 shared votes). Independents who caucus with a party count as part of it, and delegates are left out of the party tallies. Counts cover members in this site's data and may differ slightly from official tallies.

Cosponsorship

Congress	Cosponsored	Across party	Across %	Avg cosponsors on own bills	Own bills with other-party cosponsor	Share %
117th	291	37	12.7	4.5	15	30.0
118th	266	25	9.4	5.2	10	25.0
119th	227	18	7.9	5.3	3	6.2

Cosponsorship counts bills and joint resolutions only. A cosponsorship is across party lines when the cosponsor and the bill's sponsor are in different parties; independents who caucus with a party count as part of it, and members outside both caucuses are left out of the percentages. Totals can differ slightly from Congress.gov because of withdrawn cosponsors. The 119th Congress is still in progress.

A party vote is a roll call where the Democratic and Republican majorities took opposite sides. Unity % is how often the member sided with their own party's majority on those votes. Sponsored counts bills and joint resolutions only. Became law means the bill itself was enacted; bills whose text was folded into other legislation are not counted. The 119th Congress is still in progress.
