I don’t know if the line of attack is a winner or a loser. I don’t think it’s particularly relevant: Heidi Cruz is not running. Ted Cruz is, and we have more than enough information to dismiss him as a globalist shill. I also don’t like bringing family members into it.
Frankly, I don’t think Ted Cruz is worth the bandwidth. He has probably scuttled his own campaign. No sense getting all that excited about sixth place and floundering.
Yes Cruz has hurt himself badly with the activist base. About the only think Cruz had going for him was that the activist base loved him. Without that he’s toast this cycle. I do think Mrs Cruz leaned on him hard. How often has Cruz voted one way with Sessions, Lee and Paul all voting the other way? Only this time as far a I can tell. I might be willing to take another look at him but in 2020 not 2016.
