It’s not actually possible to garner support from the far right by appealing to them without going far to the right on every issue. They aren’t undecided voters, winning them over requires being farther to the right than the candidates they already support.

Go to the right on Israel without going to the right on trans issues, environmental issues, immigration, regulations, taxes, etc then they’ll ignore you. Why vote for diet right-wing when they can vote for the real thing?
