My primary point is that this race must turn into a one-on-one in order to defeat Trump. I also am saying this has to happen prior to the upcoming Super Tuesday. Now it doesn’t have to be Cruz who stays in and Rubio and Kasich who withdraws. Any one of the three can stay in as long as the other two withdraw. Any one of the three can defeat Trump if it becomes a one-on-one. The reason I suggest Cruz must stay and the others withdraw is because Cruz is consistently winning some (and getting stronger) while the other two are losing all or almost all (and continuously getting weaker). Though if they agree amongst themselves that either Rubio or Kasich should remain in, that would work too. But it is highly improbable Cruz would agree to withdraw considering he is significantly doing better than Rubio and Kasich (and winning multiple States).
Personally, I would prefer Cruz to be President over the other candidates, but nevertheless prefer Rubio to be the Republican nominee since he is stronger than Cruz in the general election. But what I am commenting here on is the political realities, not my personal preferences. Trump will almost certainly lost the general election. And he is a bad person to be President.
There is a serious likelihood that Rubio will lose his homestate of Florida and/or Kasich will lose his homestate of Ohio. Both to Trump. And since they’re both winner-take-all, Trump winning both will make him instantly the almost absolute certain nominee after this Tuesday. So if all three anti-Trump’s remain in the race this Tuesday there is a strong possibility, and even likelihood, Trump will have effectively wrapped up his victory with his wins in Florida and Ohio.
