Greg Selinger briefly spoke to the media for the first time earlier today at the legislature. It is definitely starting to look like he will run. He had spent most of this week on the phone and it looks like he has the support needed to make a run at the leadership.
Persistent rumors at the legislature also indicate that Gord Mackintosh is seriously considering running.
Nancy Allan has also confirmed that she will not be running for the leadership.
Others will also be making their intentions known in the next day or two.
UPDATE: Bill Blaikie has also just confirmed he is not running.
