McDonnell enacted the largest tax hike in Virginia history after explicitly promising not to do so.
Failing to hold him to account gives moral support to those who want Hillary to escape accountability. He is a terrible example for the case you are trying to make.
You want him to be prosecuted and thrown in jail because he broke a campaign promise? If we did that to everyone politician who did so, we would not have any politicians left.
Wait.
I think you may be on to something.
