There are warning signs that Nevada could be Iowa all over again

• "Campaigns said they still have not gotten the party to offer even a basic explanation of how key parts of the process will work."
• "Volunteers are reporting problems with the technology that’s been deployed at the last minute to make the vote count smoother."
• "And experts are raising serious questions about a tool the party has been feverishly assembling to replace the one scrapped after the meltdown in Iowa."
• “It feels like the [state party is] making it up as they go along,” said one Democratic presidential aide."

The other side: “We are confident that they are doing everything they can to implement lessons learned in Iowa," DNC spokesperson Xochitl Hinojosa told the WashPost.

The bottom line: Campaigns will be made or broken over the next few weeks, and another electoral disaster like Iowa's could create headaches that affect the entire field.
