A shift in favor of Republicans? From Pew:

The turnaround in ratings is particularly significant among independents, and the shift in independent views occurred over the course of the convention period. Independent voters now have equally favorable opinions of both parties (50% for the Republican Party, 49% for the Democratic Party). GOP favorability is up 12 points among independents from 38% in August. In contrast, ratings of the Democratic Party are down seven points among independents from 56%. The 18-point advantage in favorability that Democrats had among independents going into the conventions has now disappeared.
