Beck and Cruz have shown they have no ethics. "My family doesn't have health insurance," Cruz said, then hours later his spokesman said, oops, yes he does. Just one of dozens of examples.
BECK otoh---Career Shock Jock/Morning Zoo Host. Nothing else to say.
From what I read it can be an effective GOTV tactic, but it can also backfire. The type of person Cruz has been trying to paint himself as- this type of tactic besmirches that, and is not smart at all. Besides which, if you ARE the type of person you are trying to portray yourself as (all good and kind and Christian and honorable)- would you send out this type of mailer??? ?
