mulcair certainly knows what he's talking about, but is wrong about almost all of it.
trudeau doesn't appear to really know what he's talking about, but is mostly right and pretty much across the board.
and harper neither knows what he is talking about, nor is he correct on most issues.
it took me weeks to forget about how truly awful trudeau was in the first debate, and while he was not much better here, the difference is that mulcair was a lot less effective without having may to play off of.
trudeau: C-
mulcair: D-
harper: F
the choices are throwing the calculus that they've spent the last 20 years constructing into the trash heap.
correlations will melt away into the sea, exposing no causal factors.
it will be back to the drawing board, as the archetype says.
