I'm not sure how I feel about this. If it was my estimation that the two political parties were more interested in what is best for America, rather than just winning their ideological war, this would hold more weight for me.
Snowdon seems the logical "other pardon". Not sure I'd like that to happen. Would prefer a trial where he would be allowed to make his case. Manning wasn't afforded that opportunity either.
Neither case is at the instigation of a foreign government. So the issues need to be gone through in an open court so the country can understand the issues. And legally decide whether a crime was committed, or these were justified acts done by patriots.
I wouldn't be shocked if Trump pardoned Snowden, it would make Russia look good by justifying their harbouring of Snowden and it's just the sort of PR splash/distraction that Trump loves.
Not sure about Assange though, Trump's lovefest with Wikileaks will come to a very quick end if they ever dump something that he wants hidden. In fact, aiding the election of someone who's campaigned on the vilification of the press may be one of the more short-sighted things that Assange has done.
