Was that ever formally recorded? EDIT: I see that Guido Fawkes had a spreadsheet - so you're right. The following bit does still apply I'd suggest:As in when it went to the membership, more mps that supported the other candidates backed Truss than Sunak. She ended up with more endorsements.
That may well be because they knew she was more likely to win the membership vote, however the erg were always going to be more aligned to Truss so it’s reasonable to assume she’d have had more anyway.
I guess there's always the issue that she was so far ahead with the members, that it was a foregone conclusion as soon as it was her v Sunak. At that point, openly backing the guaranteed loser would have been a bit foolish (although in hindsight, very lucky!)
