A sad way to end a campaign. I've defended him from anonymous accusations and opportunistic ones, and this charge of an affair is not sexual harassment. I've concluded he wasn't serious on the issues.
But why embark on this entire effort if you knew there was kind of relationship, or even a question about it, in your past--apparently recent past.
Why would you do that to your supporters.
Why would you do that to your wife of 40 years.
