“Do they ask sanders/clinton the same questions?”
As a matter of fact, they do, at least for this particular question, and during the first Democrat debate their answer is absolutely, 100%, unabashedly, unequivocally pro-amnesty, so there’s no need to ask it of them anymore.
The reason they hammer Cruz on this is because he refuses to give an yes or no answer, unlike Trump, whom they DON’T bother to ask this anymore because Trump too has made his position crystal clear. Cruz is dodging and weaving on this issue, which just happens to be THE most important campaign issue for the 2016 elections, and the media senses weakness, and attacks Cruz like a Lion attacks a wounded Wildebeest.
Great points!
