In an interview with ABC' "This Week" Sunday, Sen. Bernie Sanders pushed back on the idea that he and Sen. Elizabeth Warren are interchangeable candidates within the 2020 Democratic field, arguing that Warren is a "capitalist through her bones" and he is a democratic socialist.

JON KARL: What do you say to those who say that they would pick her because she's 8 years younger than you, she didn't just have a heart attack, and, look, in the positions you're pretty much the same.
SANDERS: Well look, everybody, every American is going to make his or her own choice about the candidate that they want. Elizabeth Warren has been a friend of mine for some 25 years, and I think she is a very, very good senator. But there are differences between Elizabeth and myself. Elizabeth, I think as you know, has said that she is a capitalist through her bones. I'm not. ... And the reason I am not is because I will not tolerate for one second, the kind of greed and corruption, income and wealth inequality, and so much suffering, that is going on in this country today, which is unnecessary.

Why it matters: Sanders and Warren appeal to a similar progressive base of the Democratic Party. But while Sanders' support seems to have largely hit a plateau, Warren has continued to rise in the polls, overtaking the more moderate Joe Biden in the national RealClearPolitics average of polls last week for the first time this cycle.

Between the lines: In a recent CBS News poll of Democrats in early voting states, 43% said that the 78-year-old Sanders — who recently had a heart attack — is "too old to serve effectively as president." 28% said the same of the 76-year-old Biden, while only 4% said so for the 70-year-old Warren.

Amazon does not sufficiently distinguish between its search results and paid ads, potentially "deceiving millions of consumers," according to a complaint filed to the Federal Trade Commission.

Why it matters: Joan Moriarty, research director for the Strategic Organizing Center, a coalition of labor unions that filed the complaint, told the Washington Post the group is "very hopeful" that the FTC will investigate the complaint because Lina Khan (D), a known Amazon critic, is now chair.

Pfizer-BioNTech: Booster doses more effective at blocking Omicron

Pfizer and BioNTech said Wednesday that two doses of their COVID-19 vaccine were significantly less effective at neutralizing the Omicron variant in early lab tests, but a three-dose regimen was more effective.

Why it matters: Omicron, which has been labeled a variant of concern by the World Health Organization after being identified by scientists in South Africa last month, has forced vaccine makers to reassess the effectiveness of their vaccines against this specific new form of coronavirus.

President Biden today launched a new website and unveiled bold new branding as part of a nationwide tour to sell the benefits of his infrastructure package.

Why it matters: The White House says passage of the new law shows the ability to "forge bipartisan consensus and prove our democracy can deliver big wins" even in these toxic times.
