What these numbers mean

GUIDE

WITH PARTYHigh isn’t extreme.Counts only votes where the parties split. A moderate in a disciplined caucus can still score 95%. Check which votes they broke on.

MISSEDAbsences have reasons.Campaigns, illness and family leave drive most absences. Typical members miss about 2%.

BILLSVolume isn’t impact.Most bills never get a vote, and leaders rarely sponsor any. Many ideas pass as amendments inside bigger bills.

SCORECARDNot an approval poll.Nets positive against negative ratings of recorded actions on ChamberLight. Heavily covered people swing more.
