party-line votes with their party (when the two parties split)

3 of their 56 breaks with their party came on bipartisan votes, where most of both parties voted the same way, so they don’t count against the party-line record.

Lobbying groups they vote with

Sen. Izaah Knox’s contested votes in the 2026 session, compared with the sides 80 organizations registered on those bills.

Each legislator’s last floor vote on a bill is compared with the side the organization registered on it (its latest declaration; undecided doesn’t count). Only contested votes count, where at least a tenth of the chamber voted the other way, since most bills pass nearly unanimously. A vote on an amended bill may not be the version that was lobbied. Organizations with fewer than 3 such votes aren’t listed. Lining up with a group doesn’t mean it swayed the vote.
