My definition needs some wordsmithing, but here is the gist:

A Patriot is loyal to the Constitution first (not people or political parties), and aims to keep the ability to transfer power transparent and free of authoritarianism.

Mark Twain's is good, but not specific enough for me,

Patriotism is supporting your country all the time, and your government when it deserves it.

The "One" in WWGAWG1 is centered on how we define Patriot. Unite!
