Your statement only says you’re looking to justify voting for djt who is the worst choice as POTUS in America’s election history. Harris is not even in your decision making.
If you really need to justify choosing djt on the open you know without doubt you’re about to make the absolute worst choice by supporting djt.
It’s a terrible dilemma you’re in having to choose what you know is the best choice but your worst impulse will win out. Good luck.
