“But there is no one worth voting for.”
That is wrong.
“But I want to vote for this person because they promised they will do this or that for ME.”
This is wrong
For the first statement, God is always worth voting for and is always on the ballot.

To the second, If you are voting for yourself reward then you are not following the Bible. We are to place all others before oneself. Our reward is not of this earth and to seek after a worldly reward is seeking a reward from he who is in charge of the world, which by the way is not God.
