"Among Democrats, Hillary Rodham Clinton still has a lead but rival Barack Obama has started to close the gap."
Shouldn't there be a comma before "but", since "Hillary Rodham Clinton still has a lead" and "rival Barack Obama has started to close the gap" are two independent clauses?

It is a simple compound sentence. The word "but" is a conjunction joining the two thoughts. "And" is also a conjunction.

That sentence falls in the catagory of having a double predicate (since "Among Democrates" is considered the subject), in which case the comma is optional.
