This is plausible, thanks. Followup question for the first part - why do bookmakers favor Rubio over Cruz? Cruz has advantage in polls and IA (30× difference between their odds), but disadvantage in NH (4× difference). I could see "non-Trump voters will tend to go to anyone except Trump when their candidate drops out", but "will tend to go to Rubio" seems rather more specific.
Rubio has more support of the Republican establishment.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
