In the primary election, you are asked to "nominate" candidates, but this is not a "nomination" process in the usual sense of the word. Rather, this is a primary election: the eventual candidates will be those who receive the most votes.
The primaries function to identify candidates for each voting unit. This selection process is not the final election for members to the Bloomington Faculty Council.
If you have time, you may want to talk with others in your unit about who would be an especially good representative. When you go to the ballot, you will see that you can nominate multiple individuals to be candidates for your own "unit."
