Breaking glamours is one of the most ethical acts we can do magically in a political situation. If you truly set your intention to break a glamour, then if you’re mistaken, and there’s no glamour there, no harm is done. The energy just dissipates. If you are correct about there being a glamour there, then you are helping the truth come out, which contributes to an informed electorate and better democracy. If, however, you are truly doing a spell to force other people to see your candidate in your way, you are being unethical. Examine yourself, your mind and heart and intentions, before you try this to make sure that you can do it ethically.
