The obvious interpretation is 'higher than personal gain / power'
What I take it is 'higher than my country' -> i.e. the one-world lefty utopia BS, Soros ... higher than the Constitution.
All of them have their own reasons for hating the country, but they sure do seem to disdain it.
Comey is loyal to Progress, a leftist idea/goal that supersedes the Constitution.
Comey is thus a traitor, like his boss, the Muslim Traitor, and his wantedtobe boss, Crooked Hillary.
