Donald Trump received no significant bounce following the Republican National Convention, according to the latest NBC News|SurveyMonkey Weekly Election Tracking Poll. Hillary Clinton still leads Trump by a single point: 46 percent to 45 percent. These numbers are unchanged from last week.I note this not to say that yesterday's polls were wrong or that the NBC poll is right, but merely as a reminder that we will be deluged with polls, each reported as breaking news. Don't drive yourself too crazy: Keep an eye on the polling averages rather than any one poll and remember that we won't have a clear picture of the shape of the race until August. The polls are not really predictive at all until after both conventions have been held.
