Thanks 未設定 san for your re-posting reference source.
I suppose the original sentence can't make sense because of some weird points.
in order that the original sentence make sense,
I'd modify original sentence. put comma after the word 'clarify' .
I can grasp the meaning a little more better than before.
but the structure of that part stay weird.
due to where this comma is set the meaning of original sentencce differ a litle in the Japanese translation by GT.
if you get a solution please re-post it to this section.
At the height of his influence entering the 2022 GOP primaries, Trump sought to shape the Republican Party in his image, his endorsement in competitive races ultimately coming to define, who conservative voters supported and who they didn't.
