Democratic presidential candidates stepped up campaigning in New Hampshire on Saturday with just days left until the state's primary.

The big picture: Polls place former South Bend Mayor Pete Buttigieg in a statistical tie with Sen. Bernie Sanders. Sen. Elizabeth Warren won the organizing battle at a Democratic event at Manchester's SNHU Arena "with more than a quarter of the seats filled with supporters," Politico reports. And former Vice President Joe Biden stepped up criticism of Buttigieg. Here's what else unfolded, in photos.

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.

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.
