Big bump for Clark in new CNN/USA Today/Gallup poll

A new national poll puts Clark at 20% (up from 12%), Dean at 24% (down from 27%), with a 5% margin for error.
National polls don’t mean all that much right now, and Dean still has by far the strongest overall state-by-state numbers.
But as expected, this is another indication that the story now starts to shift from Unbeatable Dean to Rising Clark — and it’s one more sign that there will be some spark in this race before we’re through.
