Former Starbucks CEO and potential 2020 presidential contender Howard Schultz blasted some of the Democratic Party's biggest 2020 candidates during a Tuesday media blitz, calling Sen. Kamala Harris' support for Medicare for All "not American" and Sen. Elizabeth Warren's "wealth tax" proposal "ridiculous."

The big picture: The billionaire told Axios' Mike Allen this week that he was "unfazed" by criticism from the left as he flirts with launching a "centrist independent" bid for the White House.

"I'm not considering this to win the Twitter primary. I believe that lifelong Democrats and lifelong Republicans are looking for a home, and they're not spending hours and hours on Twitter."

— Schultz

Sen. Warren (D-Mass.) fired back on Twitter:

"What's “ridiculous” is billionaires who think they can buy the presidency to keep the system rigged for themselves while opportunity slips away for everyone else. The top 0.1%, who'd pay my #UltraMillionaireTax, own about the same wealth as 90% of America. It's time for change."

The U.S. is now playing by China's internet rules

President Trump's crackdown on TikTok suggests that the U.S. government is starting to see the internet more like China does — as a network that countries can and should control within their borders.

The big picture: Today's global internet has split into three zones, according to many observers: The EU's privacy-focused network; China's government-dominated network; and the U.S.-led network dominated by a handful of American companies. TikTok's fate suggests China's model has U.S. fans as well.
