After a day and several replies from people. I’ve come to the conclusion that people here are ok with their party and leaders supporting genocide and they attack the questioners (instead of their party leaders) who criticize those who support genocide. Critical thinking is scarce here.
I’m shameful of humanity.
At the risk of feeding a sea lion, there’s actually a simple reason a candidate might shift their position toward voters that are already “guaranteed” to vote for them: if that “guaranteed” base grows, it provides a voting offset that could allow the candidate to worry less about losing the support of less progressive voters.
