For progressives, Monday had a very familiar feel to it.
An election victory signaled the end of a lengthy time of either inept or contemptuous conservative rule, depending on who you ask.
The outgoing candidate was reviled as a divisive force loved by a few and hated by many more.
The winning candidate was youthful, energetic, and eloquent, and represented a party coming back from years wandering in the desert.
In short, Justin Trudeau's victory on Monday felt a lot like Barack Obama's win in 2008.
