Obtuse?
Code Pink did not try to ask Cruz questions; they tried to shout him down, because they’re Code Pink. Cruz called their bluff and let them have the microphone. Then, he destroyed them with his intellect. As I recall, the feat was universally hailed on this forum.
Hundreds of BLM and other leftist agitators didn't storm the stage as they did with Trump's rally in Chicago before he cancelled. Instead Ted Cruz invited one of them up, and yes, he did nail them to the wall.
Still not the same that Trump has been facing.
If this had happened to Cruz, debating them isn't going to work. They are going to overwhelm him and his SS protection will cancel and get him out of there.
So, your comparison is totally specious.
They did not, because Cruz invited them on stage.
