The LA Times offers its take on the Florida primary date; this article actually names Gravel and Kookcinich:
Strategists for Clinton vow that the senator from New York will campaign in Florida no matter what, underscoring her intent to build a campaign for the general election. Other well-known contenders such as Sen. Obama of Illinois, Edwards, Sens. Joseph R. Biden Jr. (D-Del.) and Christopher J. Dodd (D-Conn.), and New Mexico Gov. Bill Richardson are not likely to forgo the fundraising riches of Florida, one of the country's biggest sources of campaign cash.
That means that Florida's delegates could fall to the also-rans who appear on the state ballot but face no pressure to campaign there.
Or, it could mean no candidate gets any Florida delegates. The Democratic rules also contain a provision that no candidate who receives less than 15% of the total primary vote may be awarded delegates, though party officials admit the rule is vague and it's not clear what would happen if the top vote-getters were disqualified.
Article ends with a quote that seems to point to both the Screw Iowa attitude and the ultimate unimportance of the anachronism that is the national convention:
"If the choice is Florida is relevant and has no delegates versus being irrelevant and having delegates, I'd choose being relevant with no delegates," Ring said. "We did this so 18 million Floridians could take part in the presidential primaries, not so a few hundred people can go to a party in Denver."
