Everybody blames Trump for everything, from DHS fights to ICE to borders and spending. But his supporters are watching what he is being blamed for, and often they actually agree with those positions. So the constant attack does not weaken him. It makes that line, “they’re not after me, they’re after you, I’m just standing in the way,” feel less like rhetoric and more like a description of reality. The more he is blamed, the more he looks like the shield.
