The findings suggest slight declines in support for Biden and Warren since October, and a modest increase in backing for Buttigieg. A majority of potential Democratic voters remain uncertain about their choices. Biden continues to hold a lead -- 35% say they would choose him -- with 23% choosing Sanders, 20% Warren and 17% Buttigieg. On health care, 28% say Sanders -- an advocate of "Medicare for All" and the elimination of private health insurance -- would best handle the issue. Biden leads the field on managing the government effectively (55% Biden, 46% Sanders, 44% Warren, 42% Trump, 36% Buttigieg).
