Trump just getting ahead of the ass kicking he'll probably get to sow doubt in his poor performance.
Also, that's a great meme. Mortal Kombat is one of my guilty pleasure movies. The second had some hilariously so bad they were good moments. And of course Speed is one of the greatest movies of all time. The sequel was so bad that no one even remembers anything from it.
This is Trump’s version of working the ref. If he comes out of the debate badly he can blame ABC. Otherwise he just claims he overcame the terrible ABC news people and performed perfectly.
