Maybe because George W. Bush didn't pull anything like this and he was President during 9/11? You can't claim that the "D" is just as bad as "R" and then forget about every other President from both parties who didn't go about indiscriminately banning people with Permanent Resident status from entering the country.

And I'll take a Law Professor over a reality TV star when it comes to protecting the Constitution and running the government while obeying the law.
