Are the Democrats violating the Constitution?

Though a throw-back to materials we read in the first part of the semester, I thought folks might be interested to see this news from today's CNN political ticker:

The Democratic National Committee is violating the equal protection clause of the 14th Amendment by allowing only four states to hold caucuses or primaries before the first Tuesday in February, a Florida attorney argued Monday before a federal appeals court.

Attorney Michael Steinberg filed suit in August on behalf of Democratic Party activist Vincent Dimaio after the DNC said it would not seat Florida delegates at the national convention because the state party defied party rules and scheduled its primary for January 29.

A federal judge in Florida dismissed the lawsuit in October, but Dimaio appealed. "You can't treat the citizens of some states differently than other states," Steinberg told reporters after the hearing. "What I tried to assert is that the DNC has the right to make rules … but the rules have to be the same for all the states."
