I'm a Wikipedia editor too, but have only created 1 page and it's quite a bit of work.
A "National" Biography is a relatively formal book that actually documents the most important people to a Nation, so a "State" version of the same wouldn't count.
We don't require a page to be created, but only that you provide some reasonable level of proof that one "could" be created if you invested the time and energy into it (which isn't necessary). However, we maintain the same general standards for a WikiTree Notable - they must be famous for "something" as a start. Having a "job" isn't really good enough. So if they were State Senator from 1972-1976 and really didn't do anything other than warm up a seat, then it's very likely they wouldn't qualify. But if during that time, they instigated an investigation into the Governor's financial misdeeds, and assisted the prosecution with getting him tossed from office or tainted his reelection, then there might just be enough evidence there to make him a Notable. So you get the idea - just a job won't work, but having a job that gave you the opportunity to do something memorable, famous or "notable" would get you the opportunity to request Notable status.
There's actors this way too. Acted a bit part here, a bit part there, never a lead, short career, a few people remember one of the parts they played, but it's more of a "hey I remember that guy" thing than if they did something truly memorable or won an award. And so guys/gals like this don't get a Wikipedia page and after consideration most times wouldn't get a Notable tag either.
So probably not a bad idea to go back and review the ones you set up, determine if they were just seat warmers or if they changed history through their position, and that will help determine if they were truly Notables or just another person who had a slightly interesting job.
