Lana just told you. Kanye is a narcissist. Kanye is infatuated with donald trump. they are both geminis, and are both constantly being scrutinized for their views and behaviors, deservingly so. So to see a fellow gemini narcissist, with power, who does and says wtf he wants with few repercussions, Kanye idolizes that because he wants that power. He's trying to normalize trump so he can normalize his own behavior.
