From CP’s wildly entertaining account of today’s briefing from the Prime Minister’s Office.

The prime minister’s spokespeople spent nearly as much time Tuesday pointing out personal similarities between the two leaders as they did discussing the issues to be raised Thursday.

“They really, at a basic level, have quite a bit in common,” said Harper spokesman Kory Teneycke. “They’re similar in age, both have young families, they’re both policy-focused intellectuals. Neither has been in elected office for a long time, when they became president and prime minister, respectively. And they both come from outside the political establishment.”

Indeed, the primary challenge on Thursday will be telling the two apart.
