http://www.lopo.it/duplicate-post-plugin/
Allows to create a draft copy of a post (or page) in two ways:
1. In ‚Edit Posts’/’Edit Pages‘, you can click on ‚Duplicate‘ link;
2. While editing a post/page, you can click on ‚Copy to a new draft‘ above „Cancel“/“Move to trash“.
Both ways lead to the edit page for the new draft: change what you want, click on ‚Publish‘ and you’re done.
