Standing for what? Unless you could prove that the Cruz campaign deliberately fed CNN a false story and then used that false story to deceive the voters, you have no case. The story originated with the Carson campaign. CNN broadcast the story. The Cruz campaign used the story to try to win over voters. Nothing unethical, illegal or immoral about it.
Except what Cruz’ staff reported to Carson supporters was NOT what CNN reported.
The issue is not about what CNN reported, it is that Cruz’ people deliberately falsified, exaggerated, misled, deceived potential Carson supporters into changing their votes.
