How do you defend the Constitution? One way is to vote for people who will keep their oath of office.
How does an elected official defend the Constitution? An elected official defends the Constitution by speaking out when and if it needs defending, by personally not undermining its purpose or intent with respect to the letter or spirit of the law as the law is prescribed therein, by doing what is necessary to remove from office those who have betrayed their oath of office.
How does a citizen protect and defend the Constitution? The same way an elected official does: by speaking out when and if it needs defending, by personally not undermining its purpose or intent with respect to the letter or spirit of the law as the law is prescribed therein, by doing what is necessary to remove from office those who have betrayed their oath of office.
Who has betrayed their oath of office? Elected officials betrayed their oath of office if they did not speak out when and if the Constitution was in need of defending, if they personally undermined the purpose and intent of the Constitution with respect to the letter and the spirit of the law as the law is prescribed therein, or by not doing what was necessary to remove from office those who have betrayed their oath of office.
Citizens have also betrayed their citizenship if they knew the Constitution was in need of defending and still they did not speak in its defense, if they personally undermined the purpose and intent of the Constitution with respect to the letter and the spirit of the law as the law is prescribed therein, or if they did not do what was necessary to remove from office those who have betrayed their oath of office.
