A: Yes, but first you need a blog.
If you are a forum member you can submit a blog article to any of the political blogs if you get permission from one of the editors. You will need the blog editor to add you to the authors group for that particular blog. Alternatively they might accept your submission and post it themselves directly. You will need to ask them.
If you have a rank of at least "Absolutely Corrupt" (2000 posts) you can create your own personal blog.
You may not submit articles directly to other users' personal blogs unless you get their permission. If you would like someone with a personal blog to publish your article you will have to private message them and ask them if they are willing to publish it for you or give you access to their blog.
