A month ago, pollsters Redfield & Winton, with data collected on 2-5 March from 1 050, have:
SNP Male 36%
SNP Female 44%
A gender gap of 8 points between male and female support for the SNP.
One month later, as the SNP leadership is settled, Redfield & Winton, with data collected on 31 March – 1 April, from 1 000, have:
SNP Male 31%
SNP Female 45%
A widened gender gap of 14 points between male and female support for the SNP.
Redfield & Winton have no earlier polls to compare with but three YouGov polls in the second half of 2022 have no sign of a gender gap like this with support equal or even slightly stronger for male respondents.
While this cannot be definitive as yet, there is a clear suggestion that the SNP leadership change is weakening support among males only.
