> A vote for DeSantis only improves his chance of winning in your case, it doesn't harm Trump But imagine that 3 Bernie supporters all feared that most Republicans would only approve Trump, meaning Trump would beat DeSantis, so "just to be safe" the Bernie supporters decided to approve DeSantis (as well as Bernie), leading to DeSantis beating Bernie by 1 vote (whereas Bernie would have won if they didn't do that). In this example, the 3 extra approvals for DeSantis might have harmed Trump, if he had been 1 approval ahead of DeSantis (and 2 approvals ahead of Bernie) before these Bernie supporters cast their votes.
