No general election matchups in this poll, so I won't bother posting another thread about this, but they do pose several questions to the combined sample of all adults. (Note that NBC/WSJ explicitly offers a "neutral" option, so both the favorable and unfavorable #s tend to be lower than other polls.)
Sanders 24/19% for +5%
Kasich 14/9% for +5%
Rubio 24/23% for +1%
Walker 19/20% for -1%
Huckabee 22/30% for -8%
Paul 20/30% for -10%
Clinton 37/48% for -11%
Cruz 19/31% for -12%
Christie 24/37% for -13%
Bush 26/40% for -14%
Trump 26/56% for -30%
The weak Clinton #s mirror what we saw with Quinnipiac. Though it could be worse. She could be as unpopular as Jeb Bush or Donald Trump.
Another telling set of #s here:
Democratic Party: 38% favorable, 38% unfavorable
Republican Party: 28% favorable, 44% unfavorable
