Perhaps the most influential anti-immigration think-tank in the United States is the Center for Immigration Studies (CIS). Their analysis of the Protect the Southwest Border Act of 2014 (H.R. 5230) is making its way around the Internet with everyone from National Review to commenters on these pages parroting its findings.
It seems clear that many of those on the right who object to the bill are relying on the CIS analysis, but have not actually read the bill themselves.
I have read sections of the bill, particularly sections which I see conservatives frequently objecting to, and find the CIS analysis misleading.
As writing long analyses of legislation is not my idea of a good time, I will focus on a few narrow points where I believe conservatives are being misled by CIS.
