The politically influential Boston Globe, dismissing Democrats running against Hillary Clinton as inadequate, and the former first lady as too cautious and tied to big business, on Sunday called for Sen. Elizabeth Warren to either get in the race or recruit a top-tier challenger.

“Democrats would be making a big mistake if they let Hillary Clinton coast to the presidential nomination without real opposition, and, as a national leader, Massachusetts Sen. Elizabeth Warren can make sure that doesn’t happen,” the paper editorialized. “While Warren has repeatedly vowed that she won’t run for president herself, she ought to reconsider. And if Warren sticks to her refusal, she should make it her responsibility to help recruit candidates to provide voters with a vigorous debate on her signature cause, reducing income inequality, over the next year.”
