Actually, all you doing is creating a backlash of sympathy for Huckabee and turning anyone reading this off to your candidate.
Ted Cruz would never be politically daft enough to use these kind of tactics.
The fact is Huckabee is well-liked by many evangelicals in Iowa because they know he is a true believer when it comes to social issues. You're not going to persuade them by mudslinging and making personal attacks on Huckabee. It comes off as anti-Christian or, at best, classless.
