David Limbaugh makes the connection:

President Bush is in trouble with much of his base for approving the sale of a British shipping firm that runs commercial container operations at six major U.S. ports to a United Arab Emirates (UAE) company. I believe the main reason he is under fire from the right is that he has a nagging credibility problem concerning his inscrutable immigration policy.

To be sure, Bush is under fire from the left as well, but their opposition has little to do with national security concerns and everything to do with partisan politics.

Most conservatives, I think, see Bush as enormously committed to America’s national security and the Global War on Terror (GWOT). But many find themselves scratching their heads over his perceived “open borders” policy.

Why, they wonder, is he so genuinely clear-sighted about the evil of terrorists and the global threat they pose to the point of fashioning his legacy-making foreign policy doctrine around an unprecedented preemption strategy, yet seemingly oblivious to the potential threat in our back, front and side yards? Why the disconnect?

Actually, to call it a disconnect is a major understatement. It’s more like a gargantuan gap in an otherwise fully coherent policy. If his driving ambition is to make America safer from our terrorist enemies, why does he risk sabotaging that objective by making us more vulnerable right at home?
