Rush will never admit that this is the same thing that Obama did, but it is.
It's especially true of Trump, who as president could run an operation to secure the southern border (without congressional support, approval or even funding) just like Eisenhower, but won't. Instead he pretends there's some nefarious impediment keeping him from doing his job, which he isn't going to have after 2020 if he doesn't get down to business.
