This is a local race decided by a few thousand votes. That means the things that actually move it are small and personal: a yard sign on a busy street, a conversation with a neighbor, an hour knocking doors on a Saturday.
If you're willing to help, here's what makes the biggest difference:
Put up a yard sign.
Knock doors or make calls.
Host a meet-and-greet. Even a few neighbors in a living room.
Talk to two people. Seriously — that's the whole ask. Tell two people they have two votes.
