Gotta be careful with that. I shared an office with an old guy once and had to bring headphones. We wouldn't talk, but he would constantly make old man noises. Coughs, grunts, snorts, etc. If I didn't block them out, they would drive me crazy like nails on a chalkboard. That said, the guy himself was really cool and I loved working with him otherwise.
He could be a union supporter though - in my experience of doing labor organizing, the younger folks are usually more pro-union, then there's a dead zone of support from the Boomers, and then the really old folks are much more supportive because they grew up when unions were more of an active force.
If Wallace is down to organize, then I'd pick him and just take the risk that he's got some shitty opinions that I'll have to work through and re-educate him on.
Alternatively, may have a shitload of good jokes and all around pleasant person to work with. Its a mix with the elderly. The sharp ones are awesome sometimes
