Depends on the time period. Legends Epic Collection: The Empire Volume 1 specifies Sidious became the most politically powerful Sith Lord in history only after declaring himself Emperor during Revenge of the Sith. So any statement about him being MVP before that would refer to his power in the dark side since the Epic Collections quote automatically cancels out any interpretation about politics.
I think there's another quote saying he was merely "on the verge" of becoming politically the most powerful guy ever before RotS, supporting that notion.

then obviously its referring to his powers as a Sith Lord; anything that Sith can do, sheev can do it better in a manner of speaking
