Elizabeth Warren's 2020 campaign will no longer accept contributions that exceed $200 from Big Tech and financial executives in an effort to keep big money out of politics, she announced Tuesday in a Medium post.

The big picture: Warren's decision has sparked debate in some Democratic circles about whether the party's presidential nominee can take on President Trump with funding sourced primarily from small, grassroots contributors.

  • Warren's contribution guidelines apply to Google's parent company Alphabet, Amazon.com, Apple, Facebook, Microsoft, Lyft and Uber, the Wall Street Journal notes.
  • The Massachusetts senator has pledged to break up Silicon Valley companies, including Amazon, Facebook and Google.
  • Meanwhile, a battle between Warren and Facebook CEO Mark Zuckerberg has been brewing as the election inches closer.

Context: With the help of the Republican National Committee, Trump has already raised more than $300 million over the first 9 months of 2019.

Between the lines: Warren is betting that shutting out big donors will attract sustained funding from grassroots donors and organizations. In the 3rd quarter, she raised $24.6 million after swearing off big money fundraisers.

Tesla CEO Elon Musk, who has spent more than a decade trying to disrupt the traditional auto industry, is sounding more and more like the man most closely associated with it: Henry Ford.

Why it matters: In his quest to build affordable electric cars for the masses, Musk is starting to embrace many of the ideas pioneered by Ford's founder — things like vertical supply chains and an obsession with manufacturing efficiency. A century ago that approach helped to popularize the American automobile by lowering the cost of the Model T.
