I suppose much of it will depend on whether Linda intends to go back to work in the family business.....which of course presumes she hasn't been working there all along, on the sly. Since she began campaigning for her first Senate run, she effectively hasn't had a job at all, instead choosing to travel the state of Connecticut "listening to the people." Now that those people have turned out her bid to represent them, it will be interesting to see how she uses her time.
If she does return to WWE, I suppose they might build a program around her failed Senate campaign; if they aren't afraid to go after Jerry Lawler's near-death experience (if it was, in fact, a near-death experience) then they might choose to use Linda's political experiences as a building block to a new program.
Personally, I can't see it. While management may have no trouble building on the failures/troubles of others, they might not have the same sense of humor regarding Linda's failures. Even worse, rather than cast Linda as a bad guy determined to wreak revenge for her political failures, they might try to make her a good guy, a sympathetic figure who came up short only because the powers-that-be ganged up and cost her the dream of a lifetime. Needless to say, that would be intolerable. I mean......ugh.
My guess is that if she goes back to work for WWE, she'll do it quietly, as a behind-the-scenes CEO.....and we won't see her on TV again. I'd be happy to have it that way, as long as she stays out of the political arena forever.
