How would we know this? Voter registration doesn't ask about careers and licenses.

What are you attempting to learn?

10 out of 10!

The question is specific - "how many registered voters are registered nurses."

The OP can Google forever and will never find the answer. Occupation is NOT listed on voter registration records.

The percentage of registered voters who actually vote is an entirely different subject.
