With Trump, it means victory in November.
With Cruz it means likely defeat.
I guess if you say it enough you think it will become true.
Can you show me where the majority of polls have Trump beating Hillary and Hillary beating Cruz? Trump has 53% of women and 40% of men viewing him as very unfavorable.
I know things change but when over half the electorate already hates you it seems a little optimistic to be declaring sure victory.
In fact in the last exit polls in MO, NC and IL a one on one between Cruz and Trump, Cruz wins all three handily.
