The Iowa field is bunched together with little daylight between a handful of well-funded candidates. Each of the four early voting states continues to present the prospect of a different winner. And, at the end of that gauntlet on Super Tuesday, a free-spending billionaire — Michael Bloomberg, the former New York City mayor — is waiting to challenge whichever candidate or candidates emerge.

It’s a unique set of circumstances that has the campaigns — and party officials — scrambling to make sense of the reconfigured landscape.

Looking at the possibility of a still-contested nomination even after Super Tuesday’s massive delegate allocation on March 3, Washington state Democratic Party chair Tina Podlodowski said mid-March will “probably matter more than ever before.”

One strategist working with a presidential candidate said, “We’ve never had a situation where we get past Super Tuesday and there’s still five people in the field,” predicting that possibility this year.
