I haven't checked every single state, but what I have seen can be generally applied to all of them.
What caught my eye on POV was this line:
ARIZONA CONSTITUTION 
Nothing. The ballot on a possible constitution ban failed narrowly. The only failure case in USA !

The bold formatting could also be contrued as POV, since it doesn't necessarily appear in the source documentation.

As for the linking, there is absolutely no reason to link each and every state to the DOMA Watch and HRC. A single link to each organization at the end of the article is sufficient and keeping with guidelines. Another example of overlinking is the link to Alabama Constitution. That article contains nothing relevant to SSM and that puts it out of context. There's also no need to link to both the entire state constitution and the specific section that pertains to this article. The code or statute links are also duplicated in the generalities links, which is all duplicated by including the full text. This supposed to be summaries. I hope that gives you enough to get started.
