WOOOT I just figured out how to post my G+ to my blogger account!!!!
1. Go to blogger settings.
2, Go to mobile and email.
3. Set up your posting by email (enter your secret word)
4. Pick either Publish email immediately or Save emails as draft post
5. Go back to G+
6. Enter what you want to post.
7. Add your email with the secret word to the share area.
The item will be posted to your blog. Unless you pick save to draft, then you have to go back to blogger and post it manually.
I don't know if this works for video or pictures, but it does for texts posts
