Another potential Liberal leadership candidate bites the dust.

Economic development minister Brad Duguid now joins Finance Minister Dwight Duncan and Energy Minister Chris Bentley as high profile Liberals in cabinet who are saying no way.

Duguid says his choice has nothing to do with the controversy surrounding the Mississauga and Oakville Gas plant cancellations, which were announced when he was Energy Minister. He also says it has nothing to do with the challenges the party faces ahead.

Duguid just says the timing just wasn't right and he wants to be there for his teenagers.

He will run for reelection.

Former Health Minister George Smitherman has also announced he will not run for leadership.

Duncan says he isn't worried about what it looks like now that some in cabinet don't want to run. He says there will be some good quality candidates that will step up.

Meantime, other hopefuls say they are still mulling over what to do.

Health Minister Deb Matthews and Municipal Affairs Minister Kathleen Wynne say they are seriously considering their options and are having the conversations that need to be had before making such a decision.

Both Matthews and Wynne are said to have campaign teams ready to go if they decide to run.

Sources have told Newstalk 1010 former Health Minister David Caplan is also seriously considering a bid for the leadership.
