You can find out if someone is "moderate" or more "extreme" on the political spectrum based on who they support in the Israel/Palestine conflict. And by extreme, I mean both the left and the right. "Teams are being scrambled!"
Challenge to anyone: name me a politician on the right that is not supporting Israel. While most left and right establishment politicians support Israel, I have only seen examples on the left support Palestine.
Therefore, there are no extreme right wing politicians.
