Nikki Haley has very few delegates. Even if Trump withdrew she will still have no more delegates and his delegates seated at the convention do not get withdrawn. So "restarting her campaign" makes no sense. She has no campaign - she has not enough delegates to make any difference.
If hypothetically Trump did withdraw, he should direct his delegates to nominate Donald Trump Jr. They are his delegates - he should have a backup plan in place of his own choosing.
Normally I don’t like nepotism, but I think Eric or Don Jr. would be a good “Plan B”.
“Even if Trump withdrew...”
You mean to say that you give credence to a stupid article at first glance?
You mean you think there is a chance Trump will withdraw after all he has invested and fought in this effort?
You accept the premise and run with it?
Talk about being suggestible.
Too bad your Pappy didn’t withdraw at the right time thus saving us from you.
