I guessed when I wrote my earlier comment, but it wasn't difficult to figure out.
Foxy: You will find the following phenomenon interesting:
The federal judge who blocked President Trump’s immigration order is described by former colleagues and acquaintances as a “mainstream” Republican who went from a career as a highly respected corporate lawyer in Seattle to an appointment by President George W. Bush to the federal bench.
He was appointed by George W Bush, a Republican of course.
Usually, not always but most of the time, presidents appoint judges according to their party affiliation.
While a number of lawsuits have been filed over Trump's action, the Washington state lawsuit was the first to test the broad constitutionality of the executive order. Judge James Robart, a George W. Bush appointee, explicitly made his ruling apply across the country, while other judges facing similar cases have so far issued orders concerning only specific individuals.
That federal judge isn't a democrat by any chance? Perish the thought.....
