Very clever of CNN to pit Cruz against Rubio Wednesday night. Adding Trump instead of Carson would have made it a real cage fight. Trump, with Bush and Kasich, is no contest...
It's done, I'd guess, for ratings. If they had Trump, Cruz and Rubio in the 1st town hall, viewership for the 2nd town hall with Carson, Bush, and Katich would be a fizzle.
Weird combination. However, I think what they are doing is putting together the three liberals (Trump, Bush and Kasich) and the three conservatives (Cruz, Rubio and Carson) so that there can be a bit of a shakedown there. It actually sounds kind of interesting.
