That has absolutely nothing to do with it.
Christie is supporting Trump and wants him to get the nomination. He is a long time friend of Trump . They have worked together successfully in the past. Christie is not dictating policy to Trump.
Graham hates Cruz. He absolutely despises him and has said so many times. He has said he is only backing Cruz to prevent Trump from getting the nomination and create a brokered convention. Graham does not want Cruz to get the nomination. He sees Cruz as a stooge to use to help stop Trump.
Graham has told La Raza that he will tell any “bigot” in the Republican Party who opposes amnesty to “shut up”. Cruz has supported Graham in this statement. He has shown he is afraid to disavow. That is the price for their support. This is what Cruz is.
Cruz is a stooge who is being used by the pro-amnesty people to stop Trump.
I am amazed that you can't see the obvious.
Both Graham and Christie are RINOs. If one is held to the standard of disavowing one’s endorsers, then that standard should apply across the board and to all candidates.
But Trump supporters don’t see it that way. Rules for thee but not for me.
