5:20 am: Coronavirus could turn US presidential campaign upside down

Should the virus continue to spread, it may become impossible for the Democratic presidential campaigns in the United States to avoid changing their event schedules. As companies cancel events and limit travel in the name of caution, candidates are taking a risk by carrying on as normal.

“I think we’ll see, pretty soon, decisions by the campaigns to limit rope line and scale back events to small-town halls and use technology like streaming to reach voters,” said Scott Gottlieb, former head of the Food and Drug Administration under Trump.

“Even if the risk doesn’t merit these steps right now, it’s important they consider the examples they set.” —Hirsch

Tom Steyer drops out of Democratic primary race after South Carolina flop

Billionaire Tom Steyer, an early proponent of impeaching President Donald Trump, has dropped out of the 2020 Democratic presidential primary race.

He failed to reach the 15% viability level to win delegates in Saturday’s contest in South Carolina, where he had spent about $20 million, according to an NBC News projection. Former Vice President Joe Biden won the primary in the Palmetto State by a huge margin, while Sen. Bernie Sanders, who is considered the race’s front-runner, came in second.

With more than 50% of the vote in, Steyer had scored nearly 12% of the vote in South Carolina.

He stumped and spent heavily in the early primary states of New Hampshire and Nevada, as well, but those efforts did not help him crack the top echelon of contenders.

While he qualified for several debates, he struggled to get beyond 2% in most national polls. During the South Carolina debate earlier in the week, he had to fend off attacks from rivals, particularly Biden, about his past investments in the coal and private prison industries.

Steyer ran on what he described as the five rights; health care, an equal vote, clean air, an education and a living wage.

The former hedge fund manager was a key financier for Democrats running for congress during the 2018 congressional midterms.

Steyer, along with fellow billionaire Mike Bloomberg, combined to spend hundred of millions on Democratic candidates. That cycle, the Democrats flipped the U.S. House of Representatives, becoming the majority.

Since then, Democrats impeached Trump, which Steyer had been calling for since the 2016 election, and Bloomberg entered the race.

Bloomberg buys 3-minute ad on CBS, NBC to address outbreak

White House hopeful Mike Bloomberg bought three minutes of network TV time to deliver remarks about the coronavirus outbreak Sunday night as he tries to contrast his leadership style from President Donald Trump’s. 

The former New York mayor’s campaign will run a three-minute taped address on CBS and NBC at about 8:30 p.m. ET on Sunday, it said Saturday. The purchase from the billionaire businessman, who has already spent more than $500 million on his campaign, shows the reach his wealth gives him as 2020 Democratic candidates criticize the president’s response to the global crisis. 

In his pre-recorded remarks, Bloomberg highlights the drubbing financial markets took this week as fears about coronavirus rose. He casts himself as a steady leader prepared for the outbreak by his experience with crises in the country’s largest city.

“At times like this it is the job of the president to reassure the public that he or she is taking all the necessary steps to protect the health and well-being of every citizen,” Bloomberg says in the video against a background that evokes a White House setting. 

It was not immediately clear how much it cost his campaign to buy time on the networks. 

The Trump campaign ripped Bloomberg over the ad and defended Trump’s response to the outbreak.

“President Trump is effectively managing the coronavirus situation and has placed the United States ahead of the curve in its comprehensive response,” Trump campaign spokesman Tim Murtaugh said. “Mike Bloomberg is shamelessly politicizing the issue and only further exposing himself as an unserious candidate. He’s a joke.”

The White House hopeful’s move follows news of the first U.S. coronavirus death in Washington state. Speaking from the White House on Saturday, Trump aimed to soothe fears about the outbreak and his administration’s actions to contain it. 

The president fueled new concerns about his ability to handle the crisis during a campaign rally Friday night. He accused Democrats of “politicizing the coronavirus” and suggested they are using it to hurt him. 

“This is their new hoax,” he said, deploying language he used during special counsel Robert Mueller’s investigation into Russian interference in the 2016 election. 

The Bloomberg ad will run two days before Super Tuesday, when 14 states hold their primaries. He will appear on ballots for the first time on a day when more than a third of all national delegates will be awarded. 

Bloomberg skipped the first four nominating contests and instead gambled on using his wealth to build support in the states that will vote Tuesday.

South Carolina primary 2020: Live results and updates

Joe Biden will win the South Carolina Democratic primary, NBC News projected Saturday, in a needed boost for a flagging 2020 presidential campaign. 

The former vice president came into South Carolina looking for a clear mandate to revive his push for the White House. Once the overwhelming leader in national polls, he stumbled in early nominating contests with fourth, fifth and second place finishes in Iowa, New Hampshire and Nevada, respectively. 

Polling averages of the Palmetto State coming into Saturday showed Sen. Bernie Sanders, I-Vt., and billionaire activist Tom Steyer in second and third place. 

Biden will now try to translate his triumph to success three days from now on Super Tuesday, when 14 states hold primaries. Sanders, the national delegate leader, has led recent polls of both of Tuesday’s biggest prizes, California and Texas. Surveys suggest a narrow lead for Biden in North Carolina, which awards the third most delegates that day.

After drubbings in the overwhelmingly white Iowa and New Hampshire, Biden said his campaign would get a boost when more racially diverse states had a chance to vote. Polls have found overwhelming support for the former vice president among black voters, though that base appeared to weaken after his struggles. 

A majority of South Carolina primary voters, or 56%, identified as black, exit polls found. Six-in-ten black voters supported Biden, while only 17% and 14% backed Sanders and Steyer, respectively. 

The former vice president got a boost in the final days before the primary when House Majority Whip James Clyburn, a South Carolina Democrat and the highest ranking African-American in the House, endorsed him. Nearly half of the state’s primary voters Saturday, or 47%, considered Clyburn’s choice important, according to exit polls. 

More than half of those people voted for Biden, the surveys found. 

Voters had a better opinion of the former vice president than any of his rivals. About three-quarters, or 76%, of exit poll respondents said they have a favorable opinion of Biden, while only 20% said they have an unfavorable view. 

For Sanders, 53% of voters had a favorable opinion, while 41% had an unfavorable view. 

Only about a quarter, or 26%, of respondents said they have a favorable view of former New York Mayor Mike Bloomberg, while 66% said they have an unfavorable opinion. The billionaire businessman will not appear on the primary ballot until Super Tuesday, three days from Saturday.
