Politics is a big part of Ms Warren’s speech to campaigning voters, where, from school gyms to house parties, she walks the public through one proposition after another. It explains its wealth tax by assimilating it to the property tax paid by the owners, only widened to the “diamonds, the portfolio of stocks, the Rembrandts and the yachts” of the super-rich.

“Right now in America there is real hunger,” Ms. Warren said at a Democratic Party event in Iowa on Sunday. “There are people who are ready for a big structural change in this country. They are ready for change, and I have a plan for it.

“I got a plan” became a personal trademark for Ms. Warren, drawing cheers from the crowd and inspiring T-shirts and tote bags. And his policy announcements also serve as fundraising opportunities, helping to boost media coverage and giving his followers more reasons to donate.

Although Ms Warren has far surpassed her main rivals in releasing detailed political plans, some are struggling to catch up.

In one day last week, Senator Cory Booker of New Jersey proposed a housing plan that would provide a tax credit to tenants, former Representative Beto O’Rourke of Texas presented a voting rights plan and Senator Kirsten Gillibrand of New York released a plan to legalize marijuana.

Mr Biden – who entered the race in late April, four months after Ms Warren – presented a climate plan last week and a education plan The week before. Senator Kamala Harris of California presented plans on teachers salary, gun control, equal pay and Abortion. Senator Bernie Sanders of Vermont posted plans on education, rural America and banking.

Mr. Sanders, like other senators in the presidential race, also draws inspiration from legislation he proposed to Congress, including his “Health insurance for all” invoice, which he introduced in april. Mrs. Harris has a bill to create a big tax credit for low- and middle-income Americans. Ms Warren likes to talk about the anti-corruption package she proposed last year.
