Now that UPI/C has updated their tracking data we can get a clearer picture of the head to head Trump/Clinton race.
Trump has lead for 19 consecutive days with the UPI/c poll leaning to Clinton and the USC/LATimes poll leaning to Trump with PPD mirroring USC poll but with a slightly less Trump lean.
This is what aggregation is all about and, according to experts, is the best measure of analyzing polls.
The aggregate lead for Trump over the last 19 days is +2.2 points. The first post debate polls shows a slight lift for Trump but a better measure will be apparent over the next days as the pre-debate respondents are winnowed out.
