“The overlap between their supporters might be a surprise, especially for Warren, who is usually portrayed as being in direct competition with fellow liberal stalwart Bernie Sanders. But Warren’s strongest support so far has come from the same group of voters that is critical to Harris’ path to the nomination.”
