LEADING THE DAY:

With the Democratic nomination all but certain, the former vice president is facing the task of uniting the party's moderate and liberal wings and bringing Sen. Bernie Sanders Bernie SandersNYT editorial board remembers Ginsburg: She 'will forever have two legacies' Two GOP governors urge Republicans to hold off on Supreme Court nominee Sanders knocks McConnell: He's going against Ginsburg's 'dying wishes' MORE's (I-Vt.) ultra-devoted supporters into his campaign. He's made some overtures to progressives in recent weeks, endorsing Sen. Elizabeth Warren Elizabeth WarrenBiden's fiscal program: What is the likely market impact? Warren, Schumer introduce plan for next president to cancel ,000 in student debt The Hill's 12:30 Report - Presented by Facebook - Don't expect a government check anytime soon MORE's (D-Mass.) bankruptcy reform plan and adopting parts of Sanders's proposal for free public colleges and universities.

Complicating Biden's outreach efforts is the ongoing coronavirus outbreak, which has largely ground traditional campaign activities to a halt in recent weeks. For now, the former vice president will have to settle for virtual events – a reality that worries some of his supporters who see his face-to-face retail politicking as his greatest asset.

Biden has already started his appeal to Sanders's supporters. In a livestreamed address on Tuesday night, following his victories in the Florida and Illinois primaries, he insisted that while he and Sanders may "disagree on tactic," they "share a common vision" for the country. "Let me say, especially to the young voters who have been inspired by Sen. Sanders: I hear you. I know what's at stake. I know what we have to do," he said. "Our goal as a campaign and my goal as a candidate for president is to unify this party and then to unify the nation."

Strategists say that showing respect for Sanders and the progressive movement he leads is a good first step for Biden.

"A big piece of this is tone and attitude," Mark Longabaugh, a senior adviser to Sanders's 2016 presidential campaign, said. "I don't want to rehash the 2016 campaign over again, but [Hillary] Clinton just had this attitude that she won so everybody needed to get on board. Well that's true. She won. But Bernie has displayed some strength among key constituencies. The key thing for Biden is to show that he's not contemptuous of Bernie or Bernie's wing of the party and that he wants them to be part of his team."

Her exit from the race follows weeks of dismally low finishes in primary contests across the country. Her decision to endorse Biden marks a change of course for the Hawaii congresswoman, who previously backed Sanders's 2016 presidential bid. In a statement to supporters, she acknowledged that she has disagreements with Biden, but said that he was well positioned to heal the country's partisan divisions. "Although I may not agree with the Vice President on every issue, I know that he has a good heart and is motivated by his love for our country and the American people," she said.

ONE HOPEFUL THING

Yesterday we told you about a number of grocery stores around the world which are setting aside hours exclusively for the elderly and those especially vulnerable to the coronavirus.

Today we're going to tell you about Tonka the Great Dane, who is spreading comfort and cheer to those quarantined during these stressful and uncertain times.

KXAN reports that Tonka, a certified therapy dog with the Dog Alliance in Cedar Park, Texas, was a frequent visitor to the area's senior community before the coronavirus outbreak. The virus isn't stopping the Great Dane's work.

While Tonka may not be able to go inside the senior facilities anymore, he's been doing curb-side appearances.

Even though this therapy dog and his trainer aren't allowed to go inside the Texas nursing home due to the coronavirus, Tonka the Great Dane is still bringing smiles to the residents' faces. https://t.co/igyLW5PtFP pic.twitter.com/gaGiCeJc1x — NBC New York (@NBCNewYork) March 19, 2020

"We learned that with the recent events all therapy visits will be discontinued for safety purposes, of course, and containment. We really missed our visits, and I thought, what can I do personally, on my own, to try and continue some of the feelgood that this wonderful dog gives to everyone? So they were kind enough to go with the idea I had," Tonka's owner Leigh told KXAN.

Stay safe and stay home, folks!
