The Conservative Home survey at the end of May 2020 rated Carlaw as the politician who least satisfies members. For some reason, the grapher has put the higher scoring Paul Davis (no idea) below him.

This is all the reporter has to say by way of explanation:

Carlaw’s collapse. Amongst the minority of respondents who have a view on the Scottish leader, his net approval has halved from +23 to +11. His colleagues are reportedly angry at his handling of the Cummings row.

I suspect there’s more to it. His florid, blustering, hectoring manner in parliament is not a good look and must be driving women away.

A YouGov poll in January put trust in Carlaw at 8%, just ahead of Richard Leonard on 6% and somewhat behind the First Minister on 46%.
