In addition the candidates agreed not to campaign there since there was no delegates but Clinton campaigned there a little anyway (surprise). Also, Obama calling Florida a "beauty pageant" since there wasn't any delegates at stake probably didn't help.
No, Florida meant nothing and Hillary's win there isn't an indication of anything. Super Tuesday is D-Day for Obama and his cadre of new found political allies. In many ways it will be a referendum on the lefts growing anger about the identity politics the Clinton's are playing. They have upset a lot of establishment Democrats and I expect we'll start seeing the results of that in polls next week. We're already seeing it on the endorsement front.
