No.
Jeb! remains “in the race” because SOMEBODIES (his financiers and ?????? in the GROPe Party) want him in. Until the convention?
How can they be so stupid as to imagine (dream ?) that ANYBODY after a broke convention would “solidify” behind a “Party-selected” candidate who basically only cheated his way past the voters?
If the GOP pulls a brokered convention and Jeb or one of the other establishment candidates is forced upon us, I see both Trump and Cruz saying, “F this!” and running together on a third party ticket. At that point, I wouldn’t care who is Pres and VP.
