Gingrich is looking good. I would assume that at some point the other people who want to be President will start using the time tested political campaign tools against Gingrich, like negative tv ads.
There might be a sizable pro-divorcing your wife on her deathbed (I know, the tumor wasn’t cancerous, etc) constituency, but I’m guessing there are very few who would be “More likely to vote for Gingrich if they knew that”.
