Broad-based appeal lifted former South Bend, Indiana, Mayor Pete Buttigieg in the Iowa Democratic caucuses while younger participants, strong liberals and issue-focused voters pulled for Sen. Bernie Sanders. Former Vice President Joe Biden ran well among seniors in the ABC News entrance poll, but struggled mightily in some key groups, including those focused on electability.
The entrance poll results – reflecting initial preferences rather than the final outcome of the caucuses – represented a boost for Buttigieg while marking challenges facing Biden. CONT.
