If Cruz makes it to the debates he will devastate the rest of the field.
What Trump needs to do is use video of American victims of illegal alien crime. Get clips of the victims families.
Allow them to tell all how their families were destroyed by illegal alien crime. Trump simply pauses during interviews for the clips as they tell the audience their horrific stories. Bring on the parents of the small kids and the murdered who were viciously brutalized.
We can can sit back and watch the tables get turned on the media. Make those who lie about the truth hear and see the brutal truth.
With any luck Cruz and Trump will double team Jeb, Walker and Rubio. They need to knock those three out and then the two of them can sort it out down the line.
