I just did a site search on apnews.com for "ex state senator". They do typically seem to say, so I don't think that they avoid listing party affiliation as some kind of practice for retired state senators:

EDIT: Oh, as someone else pointed out, they indicated it in OP's article too, just in the caption. At least one of my above articles mentioned it in the caption too. So probably just a normal article.
I don't have an Instagram account and have no intention of making one, but he does have a post that I can see a low-resolution image of on Instagram that he and some other Republicans in North Dakota signed objecting to anti-LGBT language in the party platform, so I'd say the opposite, at least on the sexual orientation front.

Don't see anything doing date searches with Google either, though I'd guess that state senators probably aren't normally all that high-profile.
