You can't "walk back" a suggestion to deport 1.5 million muslims [View all]
Just like you can't walk back advocating banning the entry of all Muslims into your country.
A decision of that kind of gravity and consequences for an entire demographic of people has to be gotten right the first time by a president.
This illustrates Hillary Clinton's "loose cannon" description of Trump perfectly. It takes a loose cannon to fire in the direction of an entire group of people and then try to "walk it back".
That GOP leaders are even flirting with granting their support to someone who thinks such pronouncements and decisions effecting the lives of millions can be made and retracted with the ease of canceling a meal is despicable.
You get such decisions right the first time by granting them the level of thought they deserved the first time.
No one should be supporting or endorsing someone who gives such decisions so little thought he has to "walk them back" later.
You can't walk back suggestions like that as a leader of the free world.
