Nationwide, Gallup’s data says Americans split evenly — 39 percent to 38 percent — on whether migration benefits the nation, even though polls showThe rising opposition is fueled by the public recognition that migration shifts wealth from millions of ordinary Americans toward older investors living in coastal states.That downturn came as the party’s voters overrode the business-backed GOP leaders and installed immigration-skeptic Donald Trump as party chief and then president.
The parties had broadly similar internal splits over migration from roughly 1993 up to 2012 when President Barack Obama openly sided with pro-migration groups during his 2012 reelection. Since then, most Democrats have supported more migration. By contrast, 40% of Democrats want it increased, while just 18% want it decreased — a +22 net preference score.
