If Cruz felt that Trump’s personal attacks voided that pledge, which I can undersand, the principled thing to have done was to have publicly repudiated the pledge months ago and stated the reasons why.
But he didn’t do that. Doing what he did last night showed me that Cruz is a man who cannot be trusted to keep his word.
End of story.
Hey, Ted
If you don’t want to endure personal attacks, don’t get into politics.
My grandfather was an accomplished and upstanding man. His party (old school Democrat) was always after him to run for Mayor or County Commissioner.
He never did. Precisely because he did not want he or his family to be the focus of personal attacks.
