So your contention is that Cruz, who opposes and is opposed by the GOPe, is fighting a battle that he mathematically cannot win (he’s been eliminated).
And in doing so, he will potentially be a roadblock to ANOTHER candidate who the GOPe opposes virulently.
So, because he can’t win on the first vote, he’s going to try to prevent another person doing so as well - even though both are hated by the GOPe.
If that is what passes for the Cruz style of logic, then heaven help us!
Thus the problem.
The old adage; kill two birds with one stone; comes to mind.
The stone thrower has just one stone and the birds are not aligned.
What to do?
Just whack the little bird enough to get it to attack the Big one!
While they are fighting, you can rush in and grab the prize!
No, Cruz has not been "eliminated" from any subsequent ballot.
So, because he can’t win on the first vote, he’s going to try to prevent another person doing so as well - even though both are hated by the GOPe.
Just because both are opposed by the GOPe does not mean the two are interchangeable. Cruz is playing the game as though it will go to a second ballot. Trump is not. So regardless of what Cruz does, Trump will be screwed if it goes to a second ballot. And that will be 100% Trump's fault.
If Trump can't win unless Cruz withdraws, then Trump hasn't won. Meanwhile, the GOPe has cycled between three different candidates hoping to win a second, third, or fourth ballot. And they know they will have Trump delegates to help them out because Trump did nothing to stop them. Nothing. And whose fault is that? It certainly isn't Ted Cruz's fault.
