Steve Scalise returns to the Capitol

Sen. Bernie Sanders won so big in the Nevada caucuses that Democrats are hard-pressed to sketch a way he's not their nominee.

Driving the news: With 60% of precincts counted (slow, but better than Iowa!), Sanders is running away with 46% of delegates — crushing Joe Biden's 20%, Pete Buttigieg's 15%, Sen. Elizabeth Warren's 10% and Sen. Amy Klobuchar's 5%.

Pete Buttigieg's campaign wrote a letter on Sunday asking the Nevada State Democratic Party to release early vote and in-person vote totals by precinct and address certain caucus errors identified by campaigns, The Nevada Independent reports.

The big picture: The campaign alleges that the process of integrating early votes on caucus day was “plagued with errors and inconsistencies,” and says it received more than 200 incident reports from precincts around the state.

As the novel coronavirus continues spreading globally and China grapples with a limited production capability, there's a growing risk to about 150 prescription drugs in the U.S., sources tell Axios.

The big picture: The coronavirus has spread to more countries, with both South Korea and Italy stepping up emergency measures amid rising case numbers on Sunday. COVID-19 has killed at least 2,467 people and infected almost 79,000 others, mostly in mainland China.
