The Note: Democratic race consumed by politics of race

The TAKE with Rick Klein

New disagreements over old but raw societal divisions are dominating the Democratic race for president.

On the eve of the first debate of the 2020 cycle, two prominent white candidates are finding themselves sidetracked by issues involving race.

South Bend, Indiana, Mayor Pete Buttigieg has had to curtail some of his campaigning while coping with the fallout of a police-involved shooting. His exchanges with members of his own community have been tense, including at an NAACP-organized town hall on Sunday.

Former Vice President Joe Biden, meanwhile, spent much of his weekend in South Carolina trying to clarify his comments about political partnerships with long-deceased senators who were notorious segregationists.

Sen. Cory Booker isn't accepting Biden's contention that his words were taken out of context, saying a lesson about the power of the word "boy" isn't one a former vice president should be learning now.

"We sometimes tread upon issues that maybe we aren't knowledgeable about," Booker, D-N.J., told "This Week" Co-anchor Martha Raddatz on Sunday.

There is perhaps some irony in Democrats' fighting themselves over issues of race while contending for the right to take on President Donald Trump, given his history of words and actions on the subject.

But Democratic voters and candidates alike are making clear that a vision for the future necessitates an understanding of the past.

The RUNDOWN with MaryAlice Parks

In the days leading up the first Democratic presidential debate, Sen. Elizabeth Warren's team is hoping to put a face to her surge in the polls.

Monday morning Warren's team plans to launch a new website -- "switchtowarren.com" -- featuring testimonials of voters who, yes, switched to the senator from Massachusetts.

FiveThirtyEight Editor-in-Chief Nate Silver said on ABC News' "This Week" that he would put his money on Warren over Sen. Bernie Sanders, I-Vt., to win the nomination.

"Warren right now is hurt by perceptions that she is not electable, that she might have a tough time beating Donald Trump," Silver said. "The thing is, though, that electability concerns can melt away once a candidate begins to show success and gain momentum. So I think she actually has room to grow there."

Over the weekend Buttigieg's communications adviser, Lis Smith, tweeted an image of dark clouds looming over an airport, writing in part, "nothing to worry about." It's what you might expect an adviser to say about the current state of the South Bend mayor's presidential campaign: It has been soaring over the last few months, but is now grounded by a downpour of challenges.

Last Sunday night, a white police officer fatally shot an African American man in South Bend, Indiana. Even though the events that led up to the shooting are still under investigation, how Buttigieg handles the incident will now be scrutinized by a national audience, especially considering how he has struggled to connect with the African American community during campaign events.

Buttigieg canceled several campaign events to stay in South Bend. Friday night, dozens of community members including those with Black Lives Matter signs, surrounded him as he read through a list of demands and potential solutions. Mourners weren't satisfied by his answers, and a stoic Buttigieg was heckled by an angry crowd.

The fallout continued Sunday afternoon, during a packed town hall where hundreds showed up, many with heartfelt questions about how the presidential hopeful would improve race relations. With no clear answers on how to fix a fractured city, Buttigieg is just four days away from the first Democratic debate, when he will have to prove he can unite an already divided nation.
