I like Gowdy, although I am usually in the middle shame to see such a descent conservative leave!. he would have made a great attorney general sessions is so useless.
Here's the scuttlebutt, Trey Gowdy like many Republicans in Congress have real jobs that they can fall back into in the private sector. Gowdy is going for the big buck$$$$ where he will be the # 1 sought after lawyer in South Carolina. Gowdy might even be nominated by President Trump as a federal district judge. But I bet he will go for the $$$.
He doesn't want to be a part of the swamp. He made that fairly clear in his interview with Fox. Basically he tried politics and didn't like it. Easy to understand.
