It’s August, he’s the perfect person to play both Mitt Romney and VP Joe Biden right now so Jason had better stay put until at least after November.  To leave just a few weeks before the season even starts would be so crappy.  I know that he has a movie career now but right now the show needs him more than ever, so I don’t even want him thinking about leaving right now.  In 1992, Dana Carvey had to play both George Bush and Ross Perot for the election cycle.  After it was all over, he left mid-season.  Jason should just do something like that
