I understand exactly where you are coming from. Nikki Haley is conservative, smart, pro-Israel, level-headed, a decent person, and well-spoken. She is among a small number of politicians who I respect. I very much hoped she’d be the Republican nominee and then be elected President.
However, I believe your plan to vote for her as a write-in is a mistake. Here’s why: She’s not going to win, and you’re throwing your vote away. Right now, our brothers and sisters in Israel are fighting an existential war against a cruel, barbaric, and evil enemy, one that has already taken hundreds of soldiers’ lives and the lives of over 1,000 civilians. If one candidate is more likely than the other to send Israel weapons that can save our fighters’ lives, shoot down rockets, drones, and missiles launched by our enemies at our cities, and defeat anti-Israel measures in the U.N. then I will vote for that candidate – IMO it’s literal pikuach nefesh. I have relatives in the IDF who’ve fought in battles you’ve read about in the news and I’ve been told firsthand that getting the appropriate weaponry without delay literally makes a life-or-death difference. Whether I like the candidates or not, I’ll vote for the one who’s most helpful (or least harmful) of the two. Even if the election was between David Duke and Rashida Tlaib (c”v) I’d still make a choice rather than just throw up my hands and say they’re both horrible.
If you happen to live in a state that’s a no-doubter, i.e. either the Republican or Democrat is sure to win by a large margin, then you may have the choice of lodging a protest vote. But if there’s even a chance that your state is in play, please don’t throw away your vote.
I plan on b”n voting for Donald Trump. Not because he’s won a popularity contest in my mind, not because I think he’s a great and good person, but simply for the reason I gave above. Either way, regardless of who wins the election, we certainly have what to daven for.
