Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court. (United States Constitution)
An actual traitor would have to meet the conditions set above in order to be charged or convicted.
Every right-wing ass claims on a regular basis that anyone who disagrees with golden boy Georgie or other Republicans is a traitor. These people should take the time to actually read the United States Constitution.
