Derived 24 of 28 in round 2 turnout (highest first)
Derived 5 of 28 in round 2 abstention (highest first)

Swing between rounds

Swing of the two finalists from round 1 to round 2 in Rondônia. Derived
Candidate	Round 1 votes	Round 2 votes	Round 1 share, between the two	Round 2 share	Swing (pp)	Swing in Brazil (pp)	Vote gain
LULA (nº 13)	250,667	294,446	27.74%	30.39%	+2.65	+2.80	+43,779
FLAVIO BOLSONARO (nº 22)	652,988	674,382	72.26%	69.61%	-2.65	-2.80	+21,394

Formula first_round_two_candidate_normalized_share = v1_A / (v1_A + v1_B); second_round_share = v2_A / valid_t2; swing_pp = 100 * (second - first); absolute_vote_gain = v2_A - v1_A

Definitions: swing, two-candidate share and absolute vote gain.

Comparison with 2022

Rondônia: round 2 abstention and share of no. 13 between nos. 13 and 22, in 2022 and 2026. Derived
Measure	2022	2026	Difference (pp)
Round 2 abstention (% of registered voters)	24.68%	21.92%	-2.77
Share of no. 13 between the two (round 2)	29.34%	30.39%	+1.05

Formula share = 100 * votes_X / (votes_X + votes_Y) no último turno; swing_pp = share_newer - share_older; delta_abstention_pp = abstention_pct_newer - abstention_pct_older

Comparison between cycles, not between rounds: the candidates are different, the electorate is different and rules and context changed. The difference describes the two published results; it measures no effect. The same candidacy number (the party number) was used by different people in the two cycles: the swing compares the number, not the person. Full comparison between cycles.
