As a person's commitment to the community increases, I think we should make it possible for high-reputation users to fast-track the closure of certain questions. See here for some of my rationale.

Here's what I propose (subject to tweaking). To qualify:

1. User must have 20K of reputation.
2. User must have a tag badge in one of the tags on the question.
3. Question must already have one close vote and a downvote.

If all of these conditions apply, I propose that the 20K user's close vote be binding (the closure takes effect immediately).

My primary motivation
  If experts are being driven away by the parade of low-quality questions in their tag communities, I'd like to give them some better tools to address that.
