From the ELCA website:
On this Election Day, pray for the nation’s voters that they will cast thoughtful ballots, and give thanks for all the candidates, both local and national, who cared enough to become involved.
From the Book of Common Prayer:
Almighty God, to whom we must account for all our powers and privileges: Guide the people of the United States in the election of officials and representatives; that, by faithful administration and wise laws, the rights of all may be protected and our nation be enabled to fulfill your purposes; through Jesus Christ our Lord. Amen
