Washington (CNN) Our weekly roundup of the news, notes and chatter about the prospects for the next Democratic presidential race:

Vermont Sen. Bernie Sanders is set to hit the road on a three-city Midwestern tour designed to show that his progressive policies have universal appeal.

Sanders will be in Indianapolis on Monday for an event with union leader (and Trump Twitter target) Chuck Jones. Then he'll head to Portsmouth, Ohio — in a county Trump won by 37 points and which has been ravaged by the opioid crisis — and then Detroit, for an event with Rep. John Conyers.

What do Sanders and Conyers have in common? Single-payer "Medicare for all" health care, of course. Conyers sponsored the major House Democratic proposal. Sanders is soon expected to introduce his own version in the Senate.

If all goes according to plan, the trip could help Sanders show that "Medicare for all" sells in the Rust Belt — and it could also be a flattering contrast, one populist against another, as President Donald Trump heads West.

Kamala Harris, on policy recently. That Alex Roarty included an important quote in An additional Bernie-world note: Some of Sanders' most vocal allies had tweaked a Democratic rising star, California Sen., on policy recently. That agitated some within the party . But McClatchy'sincluded an important quote in a story this week , in which Sanders' inner circle distanced the Vermont independent senator from those allies' criticisms of Harris.

"Nobody part of Bernie's inner circle had anything to do with that, or would have any part of the criticism of Sen. Harris," said Mark Longabaugh, a senior aide to Sanders' presidential campaign.

News and notes:

BOOKER'S CONFEDERATE BILL: New Jersey Sen. Cory Booker is introducing legislation to New Jersey Sen.is introducing legislation to remove statues from the Capitol that honor Confederate soldiers in the wake of the Charlottesville, Virginia, violence and Trump placing a share of blame on anti-racism counter-protesters, as well as the white supremacists, KKK members and neo-Nazis who rallied there. "The Capitol is a place for all Americans to come and feel welcomed, encouraged and inspired," he said. "Confederate statues do the opposite."

Where's Democratic leadership? Booker has the support of House Democratic leaders, including Nancy Pelosi. But Senate Minority Leader Chuck Schumer is trying to gently nudge Democrats toward the clearer political win — fighting the President over his response to white supremacists, rather than over statues. "President Trump and Steve Bannon are trying to divert attention away from the President's refusal to unequivocally and full-throatedly denounce white supremacy, neo-Nazism, and other forms of bigotry," Schumer said in a statement. "While it is critical that we work towards the goal of Senator Cory Booker's legislation, we must continue to denounce and resist President Trump for his reprehensible actions."

Kamala Harris, who Another Charlottesville reaction of note comes from California Sen., who wrote on Facebook : "'Many sides' is what kept children in this country at separate schools and adults at separate lunch counters for decades. 'Many sides' is what turned a blind eye when Emmett Till was lynched and stood silent when marchers were beat in Selma for 'disturbing the peace.' ... It's not hard to spot the wrong side here. They're the ones with the torches and the swastikas."

GARCETTI GOES TO NEW HAMPSHIRE: Los Angeles Mayor Eric Garcetti is headed to the Granite State for an August 28 fundraiser for Manchester mayoral hopeful Joyce Craig, : Los Angeles Mayoris headed to the Granite State for an August 28 fundraiser for Manchester mayoral hopeful per WMUR's John DiStaso . Garcetti has increased his travel outside California lately — visiting Wisconsin in June and speaking at a Center for American Progress event in Washington.

Why is Garcetti interesting? 1) He is Latino and Jewish — or "just your average Mexican-American, Jewish-Italian," as he said at 2016's Democratic convention. 2) He was the first mayor in a major city to sign a $15 minimum wage. And 3) With Democrats' state-level power diminished, cities are proving to be a key source of anti-Trump resistance.

MURPHY'S LONG WALK: Connecticut Sen. Chris Murphy just completed a 105-mile walk across his state — a five-day trek that included four town halls and lots of Snapchat and Twitter updates, plus Connecticut Sen.just completed a 105-mile walk across his state — a five-day trek that included four town halls and lots of Snapchat and Twitter updates, plus daily, photo-heavy Medium posts . (It's worth keeping in mind that Murphy, though in a safe state, is up for re-election in 2018 — so this is all about his home state, not 2020.)

Rush Limbaugh playing on the radio. I'm pretty sure they're not fans of mine." There are great Murphy scenes and quotes across Connecticut media. One that caught our eye: "I have only had one guy give me the bird ," Murphy said. "I stopped and talked to a couple of guys in Southbury withplaying on the radio. I'm pretty sure they're not fans of mine."

STEYER'S HEART IN THE NATIONAL FIGHT: Liberal mega-donor Tom Steyer, whose NextGen America group is a huge grassroots organizing force on the left, has long been seen as a potential candidate for California governor in 2018 or, in what would be a longer shot, the White House in 2020. At Netroots Nation in Atlanta, he sounded like his head and heart are in national issues right now.

He called Trump's presidency a "historic moment," said America's political divide "is not shrinking, it's growing," and called the nation in "complete crisis, honestly."

WARREN'S CULTURE FOCUS: Massachusetts Sen. Elizabeth Warren unveiled a new, stump-sounding speech at Netroots Nation, declaring the Democratic Party's gates successfully crashed and the ascendant progressive wing in full control. But what raised our eyebrows was Massachusetts Sen.unveiled a new, stump-sounding speech at Netroots Nation, declaring the Democratic Party's gates successfully crashed and the ascendant progressive wing in full control. But what raised our eyebrows was how Warren weaved a cultural focus into her usual economic populism . At one point, Warren said Democrats are not "going back to the days of welfare reform and the crime bill."

Another prime example of Warren melding an economic and cultural message: "I say we can care about a dad who's worried that his kid will have to move away from their factory town to find good work -- and we can care about a mom who's worried that her kid will get shot during a traffic stop. The way I see it, those two parents have something deep down in common -- the system is rigged against both of them -- and against their kids."
