I dont recall Jimmy Carter, Dubya, Bill Clinton, FDR and Wilson being great presidents, yet they were all former governors.
I also think Dubya was better than people gave him credit for, though the only thing he did that I fully support to this day was the invasion of Iraq.
And if we are going to ding ex governors, lets call out the ex senators as well. e.g. Obama. :-D
I think Reagan would have been great whether he came from the Senate, or the governor’s office.
The man knew what he believed, and knew how to defend and advance his opinions, like Cruz.
