From a social read. If Amelia is a Sith, they would be more likely Palpatine as it would make sense for them to pass a Jedi policy the first time they’re in government, then as VC ditch a blue in a world where it’s actually 2 Sith and 1 Jedi policy to force a Sith policy through. Palpatine would usually do all they can to avoid conflicts so that they have a chance to be chancellor with 3 Sith policies on the board.
Mind you this is in a world were Sith!Amelia was actually given a choice and decided to pass a Jedi policy to look better on cards.
