34% "unfavorable" makes me wonder who they're polling and what was the wording of the question. Whatever. A lot of people who don't like Trump will vote for him. Most people have awakened to the real threat the US is under for collapse, and there isn't anyone else available who's a force of nature. Trump has as a mission to be in the history books as the dude who saved western civilization.
That's my take, anyway.
It is 61% unfavorable. 34% favorable.
From the linked poll results:
Bloomberg Politics Poll conducted by Selzer & Company. Nov. 15-17, 2015. N=1,002 adults nationwide. Margin of error +/- 3.1.
"Now, I'm going to mention some people and groups in the news recently. For each, please tell me if your feelings are very favorable, mostly favorable, mostly unfavorable, or very unfavorable. If you don't know enough to answer, just say so. ... Donald Trump, a businessman from New York."
If he gets > 5% in the Iowa caucus I will be surprised.
