He's not going to win his seat again and he knows this
What on Earth are you basing that on?
Burnaby South is an NDP stronghold, last election Sing won by ten points, with the Liberals in 2nd.
Even in what was basically a bloodbath for the BC provincial NDP this year, the NDP swept all the Burnaby ridings.
And his seat has been redistricted so as the leader of the party, he'll be put in a nearby safe seat.
So I ask you, where on Earth are you getting this silliness from?
