There are plenty of very valid arguments against secret ballot both for elections like this and general elections involving the public, as you have pointed out. However, this balloting method has developed through democratic norms and political science tradition, therefore some due care and diligence is in order if we seek to remove it.
Brazen actions without assessment consequences is what I said I take issue with, the proper way to do this is to make the necessary constitutional amendments to remove secret balloting as mandatory, while also working on some alternative procedural measures that would then need instatement. The exact nature of these alternatives I confess I can’t perceive for a lack of knowledge in this area.
If secret ballots are not wanted, that’s fine, just make sure you have the system set up to accommodate the change. And also if this call is coming from a place of sincerity and not motivated by political opportunism, then all future elections should be held this way, including when it isn’t in the interest of your preferred party. If secret balloting is being attacked for a lack of accountability and sincerity, then the people attacking it should also be motivated by accountability and sincerity, and held to that standard which they profess for themselves.
