On iNat, everyone gets one vote and the observer’s vote (or alternatively the first vote) is not weighted any higher than any subsequent votes. Additionally, having observations with IDs at a lower taxon when there is no consensus would make them more susceptible to serial agree-ers.
That being said, if it is your own observation, you are allowed to reject the community taxon, which will display your ID as the observation ID. Though, research grade will still only be achieved with a 3/4ths consensus. I personally discourage this action except for in rare circumstances.
There are many threads debating the ability to reject the community taxon. Off the top of my head, I will link one: Needs ID but has opted out of Community Taxon
In general, I would encourage other courses of action if you feel someone has made an incorrect ID on one of your observations, like tagging some of the top identifiers for the taxon.
