Your vote tomorrow will have the most influence out of any other election.
The Primary Election tomorrow will consist of only Kentucky voters, and then only voters of your party and district (for nonpartisan positions). The amount of total voters is so small compared to other elections that your single vote could actually swing the outcome of many of the races.
So if you actually want to be heard in loudest way possible, go vote tomorrow.
