Florida now has effectively legalized medicinal marijuana. This is important because cannabis has been used as a medicine for thousands of years, and possibly has coevolved with humans for that specific purpose, given selective cultivation by humans. The next step is full-blown legalization, which more states have voted to support, so that we can end the imprisoning of millions of Americans for a victimless act and relieve the courts of their burdens.
Also, as I pointed out before, the Clintons have sociopathic tendencies. Sociopaths can put on a good face for the public, yet still do plenty of damage behind the scenes. I tend to think where there's smoke there's fire, and with Wikileaks revealing what they have, it looks like the crimes of this family have been covered up for political reasons.
Another potential positive is that relations with Russia will warm up. This would be a good thing, since Russia is a nuclear power with the capability of destroying any nation on the planet if it so desires. There are no winners with nuclear war, contrary to what some politicians think. My guess is that Trump has serious backers in the Deep State who understand this. The fight for positioning in the Middle East will continue, but hopefully we will join forces with Russia to destroy ISIS. There is no point in toppling secular leaders in that part of the world -- this is a stupid neocon idea that simply will endanger everyone, including Israel.
Hopefully Trump will not trample on worker rights. His opposition to "free trade" could bode well for American workers, given that third-world wages drive down the wages in this country. We'll just have to wait and see.
