In a recent Hebrew video Chaim ben Pesach suggested boycotting Israel's upcoming elections because of a lack of parties advocating a pure kahanist approach.
It is interesting though that Rabbi Yisrael Ariel the #2 man in Rabbis Kahane's list, when Rabbi Kahane ran for the Israeli Knesset, told me a few years ago when I was thinking of boycotting the elections, that you have to pick the lesser of evils in the elections if the ideal isn't available.
In any case, my suggestion is that the True Right, Runs as a political party, that simple renames the enemy that Rabbi Kahane wished to expel.
The new name for the enemy, might be able to pass the legal tests set up to block Kahane from winning.
My suggestion is to nickname the enemy terrorist supporters.
