The colors are more akin to reggae music. The large hairstyle is more akin to soul. The expression and 3/4 view of the woman also vibes more towards soul or R&B.
Other good suggestions here are about scale. Try maybe just one face divided into two colors. Though political ideals are varied, most of the time, an argument is on 'one side or the other' so the idea of two/2 sides is more conceptually on key for political music. Maybe try the hairstyle divided into two colors. Definitely reduce the size. Though the 'fro has come back as a fashion statement, especially in younger people, it still seems a more soul or R&B music genre look. That is a general comment, but it's also the truth.
Think about images and words/phrases that are associated with politics. If you can listen to any of the actual music, that can provide inspiration as well.
