Nothing. Plugs is their gravy train. The more he is out there the more they benefit.
If he got out, where would his wife get a six figure salary for "managing" his campaign.
And that is just the tip of the iceberg
I wouldn’t worry about the wife. If things really got tough for them, they could always give up that $20,000 per month home near DC that they are renting, or either of the other two homes they own. Another $8 million book deal would tide them over.
