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.
