That’s a pretty big IF.
Not if Trump wins FL.
Yes, big if, but if Johnny Mailbags wins Ohio, this will signal a big momentum swing away from Trump...if the others stay in with a somewhat diminished Trump, an unsettled convention is a greater possibility...not impossible, but still unlikely at this moment!
The most recent Ohio polls only gave Trump a 5 point lead in Ohio, and that was before Rubio and Cruz started beating on Trump like a red-headed step-child.
