A former speech writer for George W. Bush was a keynote speaker this week at CropSphere in Saskatoon.

David Frum addressed a crowd of about 500 and talked about the impacts of the US presidential election on the Canada/US trade relationship.

He told the crowd he sees president-elect Donald Trump as being very unpredictable.

"Trump himself is proud of his unpredictability and that's a very dangerous thing," commented Frum. "What you want to see in the government of the world's most powerful nation, is total predictability."

Donald Trump will be sworn in as the 45th president of the United States on January 20th.
