DES MOINES, Iowa — Conversations with Amy Klobuchar and Andrew Yang supporters highlight how the order of tonight's winners in Iowa could hinge on who makes the first cut.

Why it matters: Caucus-goers will be asked for their second choice if their preferred candidate falls short of a 15% threshold — a high bar in a race that still has so many candidates.

The state of play: The frontrunners according to polls — Bernie Sanders, Elizabeth Warren, Pete Buttigieg and Joe Biden — each have been developing strategies to win over supporters of lower-tier candidates if they fall below that threshold.

  • A Monmouth University survey released last week found that 45% of likely caucus goers said they could change their mind about which candidate to support tonight.
  • “Klobuchar’s performance could be a real game changer in the final delegate allocation out of Iowa," Patrick Murray, the director of Monmouth University Polling Institute, told USA Today.
  • Biden surpassed Sanders (29% to 25%) in their polling when participants were asked how they'd caucus if Klobuchar and Yang fell short.

Voters drawn to Klobuchar's moderate brand of politics told Axios they liked the same of Biden, and at the end of the day it all comes down to who they think can actually beat President Trump in November. Some Buttigieg fans also overlap.

What they're saying: Mary Benton, a precinct captain for Klobuchar in Guthrie, Iowa, said she'd "switch to Biden if I had to."

  • "I think saving our democracy is more important than Medicare for All right now," she told Axios in the lobby of the Marriott hotel in downtown Des Moines.
  • Her husband, Tim, thinks Klobuchar can win over "post-industrial, Obama/Trump voters in the Midwest."
  • "I think a moderate centrist is important for this election as far as the electoral college is concerned," said Michael Adams.

Yang supporters we talked to expressed a wider range of second choices.

Jeff Thompson, 49, of Johnston is an independent voter who has supported Republican presidential candidates in years past, but detests President Trump and is inspired by what he sees as Yang's humanity and different approach.

  • If Yang falls short of viability, Thompson said he's open to supporting Buttigieg, Sanders, Warren or Biden but hadn't decided which.
  • "None of those would have gotten me to a Democratic caucus," Thompson said, but added that he'd back any of them in a general election as an alternative to Trump. 

Lori Wyble, 50, of Ankeny said she's drawn to Yang's message and feels that "he's kind of real" instead of a career politician. But if he falls short, her Plan B is Elizabeth Warren. 

  • "She's a woman. We need a change. And she's got balls, too."

The bottom line: Just because these supporters are ready to caucus for someone else doesn't mean the Klobuchar and Yang campaigns will end after Iowa — but it will send a signal to voters in other contests.

Pelosi, Schumer demand postmaster general reverse USPS cuts ahead of election

House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Chuck Schumer sent a letter to Postmaster General Louis DeJoy on Thursday calling for the recent Trump appointee to reverse operational changes to the U.S. Postal Service that "threaten the timely delivery of mail" ahead of the 2020 election.

Why it matters: U.S. mail and election infrastructure are facing a test like no other this November, with a record-breaking number of mail-in ballots expected as Americans attempt to vote in the midst of a pandemic.

CRISPR co-discoverer on the gene editor's pandemic push

The coronavirus pandemic is accelerating the development of CRISPR-based tests for detecting disease — and highlighting how gene-editing tools might one day fight pandemics, one of its discoverers, Jennifer Doudna, tells Axios.

Why it matters: Testing shortages and backlogs underscore a need for improved mass testing for COVID-19. Diagnostic tests based on CRISPR — which Doudna and colleagues identified in 2012, ushering in the "CRISPR revolution" in genome editing — are being developed for dengue, Zika and other diseases, but a global pandemic is a proving ground for these tools that hold promise for speed and lower costs.
