Obama will take the high road. A lawsuit would just make him martyr and give some semblance of evidence to the radical left trying to silence him and his right to free speech like the gag order. Obama really has nothing to gain but a lot to lose. He’s more coy than that based on his prior actions. I suspect that he’ll sit on that for awhile, give it its time in the media to get as widespread attention as it can, then release a statement enthusiastically endorsing her while citing her policy and character.
