Gay marriage left the station long ago and won't be returning, no matter who wins the election same goes for abortions there is an institution called Congress and the Supreme Court that stands in the way even if the Donald would try to ban anything.  Climate change is another thing, I seriously doubt whoever is elected will do anything about it (see response below).

I'm not so sure the economy has turned around other than for the few and that the ACA is going to work.  It seems like costs are dramatically going up and health insurance providers are bailing on it.  I hope we can figure something out and soon regarding health care.
