Of course the answer will be no, that is why he is focusing on a contested convention rather than expanding his current base. The fact is, the American electorate has voted against Cruz more than they have voted against Trump and so for Cruz to stay in means that it is his arrogant political ego that he serves first and foremost, not the American electorate.
I think Cruz is in the same boat as Rubio and Bush. This is their last chance at holding political office.
