For the Boston Globe:
https://www.bostonglobe.com/2020/09/21/metro/collins-trails-gideon-maine-senate-race-according-new-suffolkglobe-poll/500 likely voters
MoE: 4.4%
First ballot:
Other 1%
Refused 1%
Undecided 5%
With second choices for non-Collins/Gideon supporters (but not for people who selected 'undecided' or 'refused'):
Gideon 49%
Collins 42%
Savage 1%
Linn 1%
Refused 1%
(not including "refused [to transfer]" - keep these voters with Savage and assume they leave the rest of the ballot blank)Other 0% (but some voters)
Undecided 6%
The question only asked for second preferences, not third, fourth, etc. It led to a scenario where Linn/Savage backers picked other minor candidates and we never discerned their Collins/Gideon preferences despite them being able to rank more choices.
