Thursday’s Democratic national debate from New Hampshire, pared down to just the two remaining candidates Hillary Clinton and Bernie Sanders, was the most substantive debate to date in this already lengthy election cycle. That’s as much a function of the reduced number of voices as anything else, which viewers should keep in mind if they turn tonight to the Republican debate from New Hampshire. This one is televised by ABC News, and moderated by David Muir and Martha Raddatz, with invitations extended to seven Republican candidates: Donald Trump, Ted Cruz, Marco Rubio, Ben Carson, Jeb Bush, Chris Christie, and John Kasich. For all but the first three, this debate, and next week’s primary, are pretty much stand out or get out.
