I have a can’t miss prediction: tonight, when President Obama gives his sixth State of the Union address, he will describe the state of the union as “strong.”

Admittedly, predicting that the state of our union will be described as “strong” is about as safe a bet as you can make when es to politics. Over the last hundred years presidents have described the State of the Union (SOTU) in various ways — Good (Truman), Sound (Carter), Not Good (Ford). But it was Ronald Reagan who started the “strong” trend in 1983 by referring to the SOTU as “Strong, but the economy is troubled.” Since 1983, “strong” has been used to refer to the SOTU in 26 addresses.

Here is howthe state of the Union has been described over the past hundred years:
