But this debate veered fully into absurdity somewhere around the third time that Donald Trump told the actual truth about things that actually happened in actual history and was booed by the audience for his trouble. After stating that the Bush administration lied to the American people in order to drum up support for the war in Iraq, failed to keep us safe on 9/11 and passed up opportunities to assassinate bin Laden before the 9/11 attacks, the sheer mutual antagonism between the candidates and a furious audience caused something between Trump and Bush to come thoroughly unglued. Then, they simply began arguing like two people with mutual antipathy towards one another rather than politicians.
From there, the madness spread through the debate: a great circle of abuse spun around fast enough to fling all sense away. Rubio hates Cruz who hates Trump who hates Bush who hates Trump who hates Cruz who hates Rubio.
