Well, nobody's officially entered the race for Premier yet, though now that a convention date has been set that's about to change. Theresa Oswald, in a radio interview a few minutes ago, said that she'd be announcing her decision tomorrow, and others are likely to make their decision then as well (assuming they haven't already decided). Several have announced that they're not running, though. Judy Wasylycia-Leis, Nancy Allan, and Christine Melnick are all out, and today Bill Blaikie also announced that he won't be running. So who's left? Well, besides Oswald, Ashton, and Selinger, some have mentioned Family Services and Housing minister Gord Mackintosh, Conservation minister Stan Struthers, and Justice minister Dave Chomiak. Less likely, but mentioned in some articles, are Healthy Living minister Kerri Irvin-Ross and Rossmere MLA Bidhu Jha. And apparently Pat Martin hasn't ruled out a run either, though I personally wouldn't bet on it.
So who will win? Beats me. There are a lot of good candidates in that list; hopefully the best person will win. Maybe after tomorrow we'll have a better idea.
PS: Devin Johnston is keeping score here.
