The Washington Post’s John Wagner set up the debate earlier today:

Lt. Gov. Anthony G. Brown, who is leading in the polls, has every incentive to play it safe during the hour-long encounter, which is being moderated by “Meet the Press” host David Gregory and broadcast statewide.

Attorney General Douglas F. Gansler will get his best chance yet to take Brown down a few pegs and present himself as a more accomplished alternative.

And Del. Heather R. Mizeur (Montgomery) will have an opportunity to introduce herself to many voters with less than seven weeks remaining until the primary. Unlike her two better-funded opponents, Mizeur has not started airing television ads.
