Clinton and Sanders fight for every vote in run-up to key primary

Hillary Clinton rallied with supporters on Saturday in this California farmtown. But the real party occurred in nearby Los Angeles, where thousands of young voters gathered to see their hero Bernie Sanders.

Both politicians have been criss-crossing the largest state in the union ahead of Tuesday's primary, and while it is Clinton who is all but certain to prevail in their national battle, Sanders still appears to draw larger and more energized crowds.

The stark difference-Clinton speaking to hundreds in a high school gymnasium in Oxnard, Sanders inspiring thousands at the Los Angeles Coliseum - highlights the challenges of a candidate who turns towards her head-to-head battle with Donald Trump with only tepid support from many Democrats.
