Sen. Barack Obama (D-Ill.) on Sunday asked the Democratic National Committee’s credentials committee to seat the full delegations of Florida and Michigan at the party’s convention in Denver.

Currently, the full delegations of both states are seated but each delegate is only given half a vote after a contentious meeting of the DNC’s rules and bylaws committee (RBC) in late May that highlighted an intense rift between Obama’s supporters and those of opponent Sen. Hillary Rodham Clinton (D-N.Y.).

In a letter to committee co-chairs Alexis Herman, James Roosevelt and Eliseo Roques-Arroyo, Obama asks that the delegates of both states, which had moved their primaries up in the calendar in violation of party rules, be given full credentials when the panel meets on Aug. 24.

“I believe party unity calls for the delegates from Florida and Michigan to be able to participate fully alongside the delegates from the other states and territories,” Obama wrote.

He added that he supported the DNC’s “efforts to establish and enforce a schedule for primaries and caucuses that would broaden the opportunity for Democrats from all regions of the country and all backgrounds and walks of life to have a meaningful voice.”

The letter was sent just before the Illinois senator is scheduled to give a speech on energy solutions in Lansing, Mich. on Monday.

“As we prepare to come together in Denver, however, we must be -- and will be -- united in our determination to change the course of our nation,” Obama wrote. “To that end, Democrats in Florida and Michigan must know that they are full partners and colleagues in our historic mission to reshape Washington and lead our country in a new direction.”

The co-chairs responded that they “appreciate and value Sen. Obama’s perspective on this issue,” and the request will be a top priority when they meet later this month.
