Obama went after him hard, and Biden, specifically, ran Snowden to ground in Russia, specifically, as a political gambit to discredit Snowden. Specifically.

They announced exactly how he was going to be captured and tried, and it didn't involve the Constitutional protections afforded citizens. Snowden didn't run because he was afraid of going to court, but because the US intended to disappear him.

Snowden is afraid to go to court because, unfortunately, he has no viable defense to the charges. Snowden's defense lawyers want to make a so-called "public interest" defense, but neither the DoJ nor the courts are likely to permit such a defense. (Though, I'm unsure if a court might allow it if the prosecution failed to challenge it.) This is a well known point of contention publicly described by both Snowden and his lawyers for years now.

This is why people, including Snowden himself, can have such a high degree of confidence in the outcome of any trial. For the situation to change, Congress probably needs to modify the law.
