This is provably false. The Green Party explicitly ran on support for Palestine and voters in parts of Michigan voted for the party in decently large numbers to split the Democrat vote.

Not enough voters saw the issue as big enough to switch their votes on a national scale but that’s not a failure of lack of choice, the people spoke with their votes that they don’t care about Israel and Palestine nearly as much as other issues.
