JOHN HINDERAKER: “Whenever President Bush talked about immigration, his approval ratings went down. It was like clockwork: liberals never understood that the fatal decline in Bush’s popularity during his second term had at least as much to do with his advocacy of ‘comprehensive immigration reform’ as with war-weariness. Now President Obama has entered the lists, urging Congress to take up immigration. One can only wonder what Congressional Democrats make of this. Maybe they figure their own approval ratings can’t possibly get any lower. But Obama’s can, and they will if he keeps talking about immigration.”
