Sen. Elizabeth WarrenElizabeth Ann WarrenJuan Williams: Honesty, homophobia and Mayor Pete Trump DACA fight hits Supreme Court Democrats on edge as Iowa points to chaotic race MORE (D-Mass.) took fire from her Democratic rivals in Tuesday night’s debate over her "Medicare for All" proposal and her refusal to explicitly say whether middle class taxes will increase. 

Warren, who has surged in recent weeks into a leading position in many polls, did not directly answer a question about whether middle class taxes would go up to pay for her Medicare for All plan, reiterating her stance that total costs for the middle class would go down once the elimination of premiums and deductibles is taken into account.

“Your signature, senator, is to have a plan for everything, except this,” he added, noting that Warren has endorsed Sen.

Medicare for All plan instead of developing her own. 

Buttigieg also said Medicare for All would “obliterate private plans.”

Warren shot back with a strong defense of a full-scale Medicare for All plan, deriding Buttigieg’s optional approach as “Medicare for all who can afford it.”

“Medicare for All is the gold standard,” Warren said, adding, “I will not embrace a plan like Medicare for all who can afford it.”

Sanders, the author of Medicare for All, said it is “appropriate to acknowledge that taxes will go up,” in a break from Warren. But he argued that overall costs for the middle class will go down once premiums and deductibles are eliminated.
