Such a waste of legal resources, time and money even if Trump eventually wins. Trump is like a person who chose to take a rough rocky and dangerous road instead of the smooth highway. Just use Obama's order on the same subject that also covers terrorists and vetting, but avoids the constitutional traps. Trump could have made the vetting tougher, require more documents, etc. but the basic order could have been the same and it has worked well. Even if Trump's order had no religious issues, it would still not be as good as Obamas which focused on people and what they did and where they went and not where they were from. Terrorists can come from anywhere and not just six countries. If an applicant for a visa from say London or Detroit travelled to one of the six countries, then that might tell you something and that could be looked at. But makes no sense to use the 6 nation order and have to deal with religious issues as well.
