But, I prefer to look at the bright side (feel free to whistle the tune.)
So here goes -
Trump's election in itself proved the shabbiness of the "(S)he'll never win" argument. Now, Trump broke a lot of political rules, and ran as a Republican, so it's not likely that a libertarian could achieve the same success acting like Trump. BUT, at least the "can't win" argument - more psychological manipulation than argument - can be shelved for the next 20 years.
AG Sessions somewhat weasely stance on pot stores - given how Trump acts, the AG could have gone full stormtrooper on pot and probably succeeded at some political cost.
The recent six-month budget that provided zero funds for prosecuting pot stores.
So, admittedly three political crumbs washed down with a shot of wishful thinking, but we can at least say that the Trump administration does not have carte blanche to enforce a narrow political viewpoint.
