Until they cast their votes, he is the presumptive nominee.
Well as so many of those fools are lawyers, I guess they should have been cornered and had to pledge to support the presumptive nominee...
See, I think Cruz is purposefully being evasive ~like saying “Trump will not be the nominee” every time Cruz was asked if he would support Trump instead of saying, Yes, I will support Trump if he is the nominee—and he gave no hint during his very odd concession speech that he would support Trump either.
From what I see, he clearly does not want to support Trump, whether he is the nominee or presumptive nominee.
