Maybe ask her what she likes or respects about Trump or the Republicans, why she feels they represent her better than the Democrats and what changes for the better she thinks they would make?
From my perspective as a cis het white guy with the privilege to vote based on my ideas about how society should be run rather than immediate self preservation...I can understand that's an attractive privilege.
