Sen. Elizabeth Warren, D-Mass., is reportedly going out of her way to be the first to reach out to Democrats after their respective election contests, indicating what could be far-reaching strategy to build a web of support for a 2020 presidential run.

According to David Axelrod, who was a top adviser to former President Barack Obama, she's calling both winners and losers on an "impressive scale."

“I speak a lot to candidates who are running this year,” Axelrod told the Washington Post. “She’s the first call they get after a primary. It’s not just the winners she’s calling, she’s calling the losers, too. … The scale is pretty impressive.”

“This is how you go about building relationships and acquiring chits for a future project. It’s very smart,” he continued. “If you were advising someone who had the resources of someone who was going to run for president, this is what you would do.”

Axelrod was a chief strategist in the Obama election efforts.

The Post report took a look at the posturing Warren might be doing to set herself up for a challenge against President Trump in two years. She has yet to announce her candidacy, stressing that she is focused on re-election in Massachusetts. However, she has teased an interest, and has become a Democratic campaign maven, helping raise millions of dollars for her allies, and has sent staffers to a number of early voting states.
