Usually its for the Cleveland Cavaliers and king james that play here but tonight its for the republicans with all eyes on trump. Will he falter will he fielt and can anyone break through . Reporter tonight, Trump Force One landing just hours before the debate, carrying not only the republican frontrunner but the entire trump clan. Welcome to cleveland. Is it true you did not prepare . Im not too well lets put it this way. Ive been preparing all my life. We have to make our country great again. Thats what we have to do, make America Great again. Reporter what is it like to have the bulls eye . His closest competition, governor jeb bush, earlier reaching out to a higher power. This is the main way i plan pray to my creator.

Lets get right to abcs chief white house correspondent, Jonathan Karl who is inside the arena tonight. Jon, so much talk about trump being the target. Is there somebody else on that stage candidates might be going after. Reporter for all that talk about the bulls eye on dond trump, i see no candidate coming into this debate trying to pick a fight with donald trump. He may be the obvious frontrunner right now but they dont see him as having a chance to win the nomination. They will be going after jeb bush. Still seen as the man to beat. Jon karl thanks for that. Lets get right to one other question tonight with matthew dowd. Donald trump said this. Ive never debated before. Im not a debater. He said ive never been in a debate before. What do you make of this . Thats probably an accurate statement. Hes much more used to giving orders in his previous life. Delivering it out there. Telling people what it is. When he says no debate prep youve prepped candidates for years before you became our analyst here do you believe theres been no prep. Hes been prepped. This is about lowering expectation. What every candidate wants to do is lower expectations far enough so you can exceed them so the story is in the aftermath that you exceeded the lower expectations. Thats exactly what dojd trump is doing. Thank you.
