Looking at Google it looks like the online casinos are taking prime positions and some gambling portals are slipping or gone.
This is the same on Yahoo also 
I see a few (even newer casinos) ranking well above portals with REAL content. Check those pages carefully for the casinos ’cause it looks to me like they are doing something a bit sketchy, like (possibly):
1. cloaking – i.e., feeding the SE’s a bunch of keyword rich crap and then feeding surfers their homepage
2. Hiding text within the site
3. Using affiliates to rank higher (alt tags, title tags that are keyword directed)
In any case, they are ranking well and we are probably partially to blame for not removing alt/title tags from the URLs
