She holds a 7-point lead in Colorado, a 3-point lead in Florida, a 4-point advantage in North Carolina, a 5-point lead in Pennsylvania and a 6-point lead in Virginia in head-to-head polling.

Clinton also polled favourably among younger voters across the board. 

Meanwhile, in a separate NBC poll taken directly after the debate, Trump is trailing among independent female voters.

27% of likely women voters said the they thought worse of Trump since the debate while 30% said their opinion of Clinton had improved.

The survey also found that 68% of Trump's supporters haven't changed their opinion of him after the showdown.

Overall, the poll found 52% who watched the debate thought Clinton won, 21% went for Trump while 26% felt neither candidate did enough to win the contest.
