I think that Election Day is the *official* National Day of Prayer.
A Prayer for Good Government
Eternal Lord, Ruler of all, graciously regard those who have been set in positions of authority among us that they may be guided by your Spiri, be high in purpose, wise in counsel, firm in good resolution, and unwavering in duty, that under them we may be governed quietly and peaceably; through Jesus Christ, our Lord.
For Responsible Citizenship
Lord, keep this nation under your care. Bless the leaders of our land that we may be a people at peace among ourselves and a blessing to the other nations of the earth. Help us provide trustworthy leaders, contribute to wise decisions for the general welfare, and thus serve you faithfully in our generation to the honor of your holy name; through Jesus Christ, our Lord.
