Hillary Clinton scored a decisive debate victory over Donald Trump , coming off as more presidential and better prepared, according to a new HuffPost/YouGov poll .

By a 27-point margin, 49 percent to 22 percent, Americans who had heard at least something about Mondays presidential debate said that Clinton did a better job than Trump. Twenty-two percent said neither had done a better job, while 8 percent were unsure.

Those results are broadly in line with other scientific post-debate polls , which also found a sizable advantage for Clinton. (A spate of online reader polls, which Trump has touted as showing him ahead, have no scientific grounding whatsoever.)

Seventy-seven percent of those polled, including a majority in both parties, said that Clinton prepared well enough for the debate, compared to just 27 percent who said the same for Trump. Even 43 percent of Republicans said that Trump should have done more preparation.
