Barack Obama further inched his way towards the nomination this weekend, with a decent level of action on the super-delegate front.

Obama picked up add-on delegates in Colorado and Kansas, caucus states where his wins guaranteed that his supporters would be picked for the add-on slots at the state conventions. In Colorado, former Denver Mayor Federico Pena was selected, while Kansas Dems picked Lt. Gov. Mark Parkinson, who is interestingly a former chair of the state Republican Party.

Obama was also endorsed by Maryland DNC member Greg Pecoraro, the campaign announced.

For their five add-on slots, the California Democrats picked three Clinton supporters and two Obama supporters.

The score for the weekend: Obama +5, Clinton +3.
