Much of the opposition to the travel ban is politically motivated. Maybe even personal. Derrick Watson is a native Hawaiian who attended Harvard Law School with Barack Obama. He was appointed by Obama as well. 48 hours before Watson issued the injunction which halted Trump’s travel ban, Barack Obama just happened to take a trip to Hawaii. Could be a coincidence or it could be fishy as when Bill Clinton intercepted Loretta Lynch as soon as she landed in Phoenix Arizona while she was the Attorney General in charge of the Department of Justice’s investigation into Hillary alongside the FBI. And the 9th Circuit Court of appeals has a history of decisions based on liberal activism and 80% of them get overturned.
The travel ban is up for formal talks in the court in September of 2017 but for now, it is back in place thanks to the majority conservative Supreme Court. Neil Gorsuch is the first Supreme Court appointee by Donald Trump and may not be his last since Ruth Bader Ginsburg and Stephen Breyer are now elderly. Also, conservative justice Anthony Kennedy may retire soon. This situation could mean that Trump has the opportunity to appoint in total, 4 new conservative justices which would tip the scales of balance 7-2 in favor of conservatives which would help shape the direction of the country into the foreseeable future.
