None. There is zero definitive evidence of which side of the aisle he is on. The right wants him to be left and the left wants him to be right. Some on the right want justice, some want vengeance. Most on the left are celebrating either way, some didn’t agree with Kirk but didn’t believe he should die for his views.
Then you have the people in the center of the aisle that just want to be left alone and don’t care. Both the left and right hates these people.
