GOP strategist Alex Castellanos argued that polls underestimate Republican enthusiasm, citing a surge in Republican voter registration. ​“I think the pollsters are getting this wrong. We’re all missing something, because they’re giving us the same poll over and over again. There isn’t even statistical variation,” Castellanos said. ​The final NYT/Sienna poll said it will be a photo finish in the seven swing states -- Harris showing new strength in North Carolina and Georgia and Trump erasing her lead in Pennsylvania and maintaining his advantage in Arizona.
