Regardless, 29 percent of debate watchers said what they saw Tuesday made them more apt to vote for Trump, compared with 18 percent who said it made them more likely to back Clinton. However, most of the watchers Tuesday night, 53 percent, said their vote wasn’t swayed by what they had seen. After the first Clinton-Trump debate last week, 34 percent said it made them more apt to vote Clinton, 18 percent Trump.
And 48 percent said Kaine had a better understanding of the issues, edging out Pence at 41 percent. Clinton topped Trump by a better than 2-to-1 margin on that score after their first debate.
The poll was conducted by interviews with 472 registered voters who watched the October 4 vice presidential debate. Results among debate-watchers have a margin of sampling error of plus or minus 4.5 percentage points. Respondents were originally interviewed as part of a September 28-October 2 telephone survey of a random sample of Americans, and indicated they planned to watch the debate and would be willing to be re-interviewed when it was over.
