Yup.
To implement a vote where only users with access to a full node can
vote, you'd force part of the vote to be determined by a
non-miner-committed value calculatable by anyone with a full node. For
instance, a very simple toy example that would work is just XORing your
vote with SHA256(the entire blockchain)
