Hickenlooper of Colorado and O'Malley from Maryland.
Some have suggested Kirsten Gillibrand, New York and a senator who took the Hillary Clinton spot. To that, a resounding NO! She is not to be trusted. She is now supposedly anti-gun, however, early in her life as Senator, she told of guns under her bed at home. Unsecured! And she had young children in the home who could have easily accessed them. She is learning, I suppose, yet I still don't trust her and find her more of a follower than a leader.
On my extended list, Amy Klobuchar, Cory Booker and Tim Kaine.
On my no, no, no list are Joe Biden and Hillary Clinton. (By the way, Chelsea Clinton is now old enough to make a run)
