A look inside the latest numbers suggests several reasons, but it appears the president’s stand on immigration is the biggest drag on his support among Republicans—even more damaging than the disapproval caused by rising gas prices.

Of several issues specifically covered by the Gallup poll—the economy, foreign affairs, the situation in Iraq, terrorism, immigration, and energy policy—immigration is the only area in which more Republicans disapprove of the president’s policy than approve. And they disapprove by a significant margin: 52 percent of Republicans in the survey disapprove of Bush’s immigration policy, versus 40 percent who approve. ~Byron York, National Review
