Among the things to note, among NH women not voting for Trump 91% would not even consider him. Also in NH, Clinton is drawing 93% of self-identified Dems while Trump is only drawing 78% of self-identified Republicans. Johnson draws 5% and Stein 3% in the Granite state. Of those picking Clinton or Trump,64% of respondents have firmly decided and will not change, 25% are strong for their choice and probably won’t change, 9% somewhat strong and might consider changing, and only 1% thinks they might somewhat change.
In Florida, Johnson drawing 5% and Stein 2%, 34% care about Republican leaders not endorsing Trump, and 47% how Clinton has talked about her email server matters. Only 38% believe Trump is prepared to be commander in chief, and only 29% believe he has the temperament and judgment to serve as President. By contrast 53% believe Clinton is prepared to be commander in chief and the groups split on temperament and judgment 50-50.
From the news story:
In New Hampshire the numbers suggest Trump hasn't much room to grow, at least as of right now. Trump is losing New Hampshire women by a wide 51 percent to 29 percent spread, which is big enough for Clinton to easily overcome his slight edge with men.
Also from the news story:
Trump hasn't made any headway since June in allaying the concerns of Florida voters who were put off by his campaign. Back in June half of them said watching the Trump campaign scared them, and those numbers are effectively the same today. The number of voters not with Trump who'd consider him has also slipped, from 16 percent in June to 10 percent now.
The movement in Florida, such as it is, has come from Clinton pulling in those previously undecided. Although she does get a few more Republicans now than Trump does Democrats, both of their support bases have remained largely locked in, and it remains a campaign in which voters feel they don't have a lot of choice. That may in turn explain why there have been so few outright swing voters.
And the conclusion of the news story:
So the overall electoral map, based on state-by-state polling throughout the last few weeks, is starting to show a much tougher path for Donald Trump now: He cannot rely simply on flipping a few tight states to get the 270 electoral votes needed to win, but will need to outright reverse a string of Clinton leads to do so.
DUH!
Adding a few thoughts of my own. It may be only August, but a lot of people are making up their minds for good. Look again at the figures in NH — 64% of those picking Trump or Clinton are locked in, 25% probably locked in. In GA the equivalent percentages are 72 and 20, and in FL 74 and 19.
I would guess that firming up of opinion is the result of several factors, including the number of foot in mouth comments made by Trump going back to Judge Curiel, the darkness of his acceptance speech, the positive sense of the Democratic convention, and — not to be dismissed — the fact that Clinton has been on the air going back as far as the Republican convention in battleground states.
