DURHAM, N.H.—Their race newly energized, Hillary Clinton and Bernie Sanders head into the first one-on-one debate of the Democratic presidential contest Thursday night in a tussle over their very political identities.
The two candidates are sparring over who is the best standard-bearer for progressive values — and who can actually deliver on a liberal agenda of providing universal health care access, reducing income inequality, protecting worker rights and more.
“Good ideas on paper are important, but you’ve got to be able to translate them into action,” Clinton declared on the eve of the debate.
