A presidential legacy often is not known for several years after his Presidency. History will favor Obama's vision more than his execution I'm afraid. Given that we had GWB who was anti-science and President Elect Trump who denies science, he'll likely be seen as an island of truth decades from now.
Just because someone denies the skewed, disproven liberal research of 'Global Warming' does not mean someone is 'anti-science'. Despite the repeated declarations of liberals, the science has NOT been completely proven.
The fact is that liberals seek to label anyone and everyone who do not agree with them on all matters: 'Racist', 'Sexist', 'homophobe', 'anti-science', etc...
Unfortunately for Libs, in the past it has usually come to light - through such events as their own personal e-mails being leaked, for example - - that THEY are what they are accusing others of being.
