Agreed. Trump has got into his head and off his message.
Why Cruz is doing what he has is bewildering to me, especially when he now sees his numbers falling and looks to have lost SC, and NV now.
Trump has been smearing Cruz ever since Cruz became a threat. Cruz has to fight back or he looks weak. It’s a gamble but it may pay off big and at the moment Cruz is behind so he might as well take the risk.
