Voting analysis
Nancy Mace is absent from recorded votes more often than all but a couple of members of the entire House. That fact shapes everything else on this page, including the defection rate, and it deserves stating before the rest.
The figure measures participation and nothing else. Members miss votes for reasons ranging from illness and family emergency to official travel and military duty, and the record here does not distinguish among them.
A rate computed over fewer votes
Because a defection rate can only count votes actually cast, hers rests on a noticeably smaller base than most of her colleagues' — the denominator below is well short of the chamber's typical figure. The rate is real, but it is measured across a narrower sample, and it should be read with that in mind.
The departures themselves are concentrated in amendment fights: on the defense authorization, on the State Department spending bill, and on a third measure, she repeatedly backed changes her party declined to adopt.
