New Incentives in particular seems poised to spend much more after large ~Givewell cash grants

Most people view farm animals as serving a purpose, whereas animal cruelty is criticized more when more unnecessary. That's why moral progress is made in fashion, poaching, and animal-fighting sports and why veganism should focus more on food waste and traditions like egg tosses and egg decorating: https://www.vox.com/future-perfect/22890292/food-waste-meat-dairy-eggs-milk-animal-welfare Omnivores can respect farm animal sacrifices more, which is a useful mindset shift

I'd love to be able to maintain more polished current data

or Governor candidates in states like North Carolina

I don't mean most members would be interested, but I think they'd at least listen to the pitch. Just thinking similar/tangential existing organized groups seem underutilized when growing new groups

Bus routes also seem cheaper, quicker implemented, lower profile politically, and more historically ridden than rail: https://www.researchgate.net/figure/1-US-transit-ridership-by-year_fig1_367860713
