I don't know about Snowden, but Obama LOVES the surveillance police state.
Snowden is a creation of Obama. Snowden was the conduit to weaken the US and a plausible way to pass US secrets to Putin, right under our noses.
Snowden spent the Obama years in Russia; the central purpose of his 'visit' was to coordinate the breakdown Americans' trust in all facets of society (revealing spying, corruption, bad acts of previous administrations), to make way for the Utopians– you know, the guys who believe in the UN.
The other thing that Snowden accomplished was to cement Obama's (really, Valerie Jarrett's) stranglehold on the DNC. They can blame Trump and his 'Russian Connections' all they want– the anti-Hillary stuff is coming from the White House.
