Reddit does intend to have the /r/blog posts on the front page, but they don't necessarily need to rig the votes.

As mentioned in the article, the algorithm for selecting which posts appear on the homepage seems to allocate slots for each subreddit. If one subreddit has more people voting than another subreddit, they can both appear alongside each other, rather than the larger one always filling the homepage.

Since the only posts made to /r/blog are infrequent, they will always get the slot for the subreddit and will likely always appear on the front page or second page even with few votes. Then, because they are visible to many users, they can attract more votes.
