My local news is reporting Trump up 5% now on Clinton, due to Independents who were swung by the RNC convention. I don't think most of that convention swung them: it was Trump's well-prepared and delivered speech at the closing.
For Clinton to recover, it is critical that she her speech trumps Trump's.
A couple ways she can blow it:
1) Try to be all smiley or snarky. (She needs to be presidential and serious)
2) Lie (and get pounded for it in the media and comedy follow-ups).
3) Spend TOO much time on Trump fails (some is great; but more substance please)
If she can hold it together, and the background of the convention isn't as hateful as the RNC's was, I think the polls will show Independents back-swinging next week.
