That's the day the Colorado Secretary of State's office must officially certify the names on the November ballot.
Will Dan Maes, who just lost the support of former Senator Hank Brown, be there? That's the big question.
The noon taping of Colorado Decides 2010 "Gubernatorial General Election Debate" at the Colorado Public Television studios at 2900 Welton Street appears on John Hickenlooper's schedule, so count on Denver's mayor to be there; the Tancredo and Maes campaigns don't send out scheduling alerts.
But who shows up this morning -- and then how they perform -- could mark the turning point of a gubernatorial campaign that's already taken more twists and turns than the Mind Eraser.
The debate -- whoever's on it -- will air at 9 p.m. on Channel 12. It's a joint project with Channel 4. Jim Bennemann will be moderating.
