Pray, and then vote, and then pray again. Notice that you can rightly prayer more than once today, but you can only vote once today. That should give you some idea as to which is more important in the scheme of things -- but don't neglect one for the other.

If you need a prayer to start you, here's one which is good. As I think about it, this one is even better.

Then resume your life as a disciple of Christ.
