"By supporting Simpol I will be voting in future national elections for ANY politician or party – within reason – that has signed the pledge to implement Simpol’s range of global problem-solving policies alongside other governments (the Pledge). Or, if I have a party preference, I want my party to sign that Pledge. In that way, I still retain the ultimate right to vote as I please. But I am giving a powerful message to all politicians that I will be giving strong preference to politicians who have signed the Pledge, to the disadvantage of those who haven’t."
