Yes...'almost' anyone would be an improvement. I could certainly be comfortable with trusting Obama to lead and make thoughtful decisions. But, that being said, I could be reasonably comfortable with any of the top 4 Democratic candidates...including Biden, though I admit that he has no chance.
   I am more & more impressed with Edwards in the one-on-one interviews I have seen, even though his 'speeches' lack a little.
....and, unlike many, I am NOT against Hillary Clinton. I judge all candidates more by what I see of them in informal interviews, and she is no dummy and is quick-witted and knowledgeable, and despite not being absolutely clear about immigration...(and who IS?..or can be?), she is within my tolerances on most issues.

...If I had to vote, right now, I'd probably give it to Obama by a few points...but no more. He IS just coming up to speed on many issues and needs, despite his 'outsider' claims, a base in Washington and a pool of competent folks for appointments. I would REALLY like to see a list of individuals he might appoint to cabinet and other positions, as I consider that to be as important an issues as the presidency.

We shall see....I just wish ALL of them would stop sniping at EACH OTHER!
