Not to the “base” of either of the major parties, no. Those voters are already committed to their candidates.
This election is likely to come down to independents and undecided voters. Where that messaging could matter is with people who are unsatisfied with the Democratic party AND dislike Trump.
The idea that “they hate me enough to kill me” might be compelling to someone with a strong dislike of the Democratic party, perhaps enough to get them to hold their nose and vote for Trump. That being said, I wouldn’t even venture a guess at how many people that would be.
