When Trump realized he would need the delegates, he decided on the route of destruction poison the well once again it is what he does.
Everytime someone get close in this election he does a personal attack, in this case the object was the system because his last personal attack on Cruz’s wife backfired on him.
Keep spinning. If retweeting an image of her face is a vicious attack then the snowflakes have taken over the establishment.
Try a little perspective, Cruz’s surrogate tried to smear Melania in early March on National TV and the PAC followed up by distributing fliers and TV ads in a very socially conservative region to directly attack Trump through his wife.
Trump reminded Cruz that they both had wives and was extremely mild in his exposure of her Nationalist activism. She has stated that she and Ted are running for POTUS so her track record is pertinent and a legitimate area of concern.
You are either ignorant of how the RNC works at state and local level or part of the problem.
