Not all his fault, but he definitely shares much of the blame, largely due to a lack of leadership on the topic.
What the president can do in those situations is focus the discussion, he has the highest pulpit of any politician, he should’ve been using it to move the frame of discussion and shift party strategy to make court reform a stronger pillar of the party platform. When the president says something it gives other party members permission to hammer on an idea.
Instead he lingered on his dusty, worthless notions of bipartisanship and “reaching across the aisle” and wasted all his political capital defending a genocide.
