The links are to the PSL presidential campaign, which shouldn't be too surprising from a domain called votesocialist2024. The poster is meant to be agitational, to make you think critically.

These claims are all either sourced in the poster or easily verifiable public record. Walz famously cracked down on the George Floyd protests. As in, in the city(ies) where Chauvin killed him. His record includes those vetoes. And it should really be no surprise to anyone that the Democratic ticket is Zionist, the party line is support for Israel and its genocide. The only national-level Dem that consistently voices opposition is Tlaib.
