"I do think there's real questions about the mail-in option here," Plouffe said on a conference call with reporters. "These are very complicated elections to put on. In the state of Oregon which is kind of the standard for this, it took well over 10 years to get comfortable doing this statewide, to have signature verification in place, lots of alternatives for people to vote in person, there's questions around the list, both of these states have justice department review, that would need to take place, so there's a lot of questions."
The mail-in proposal is being strongly advocated by some leading Democrats including Florida Sen. Bill Nelson, who has said that it is the only reasonable and affordable option available to the state. Democratic National Committee Chairman Howard Dean has also expressed support for a mail-in vote as one way to allow the state’s delegation to be seated at the party’s national convention this summer.
"Every voter gets a ballot in the mail. It's comprehensive. You get to vote if you're in Iraq or in a nursing home," he said on CBS' "Face the Nation" Sunday.
But a majority of the Florida’s Democratic delegation said in a statement Tuesday night they oppose both a primary re-vote and vote-by-mail.
"We are committed to working with the DNC, the Florida State Democratic party, our Democratic leaders in Florida, and our two candidates to reach an expedited solution that ensures our 210 delegates are seated," the delegation's statement read. "Our House delegation is opposed to a mail-in campaign or any redo of any kind."
Speaking with reporters Tuesday, Plouffe said the campaign will ultimately follow the DNC's resolution with regards to seating the delegates. But he sharply criticized the Clinton campaign for "trying to change the rules."
"Senator Clinton said she was playing by the rules through the early sates, we played by the rules," he said. "Now when they believe it serves their political interests, they're trying to change the rules and say these elections should count for something. We think that's the kind of political maneuvering and calculation that voters are tired of."
Responding to Plouffe's comments, the Clinton campaign noted that the Illinois senator co-sponsored a bill last June that "would establish a vote by mail grant program."
