Zeke's Averages of the Averages
I've dropped Virginia, Florida, and Texas off this chart for now because on average they're all just on or outside the margin of error, and also because they all have so few polls that some of the averaging sites don't even have a number for them at this point, and clearly the pollsters don't think they're too worthwhile to poll much.
There's actually been some major movement here at the state level, but i'm not sure that has anything to do with a convention bump - a lot of polls dropping right now are pollsters that haven't done any polling since the Biden/Harris switcheroo, so many of these are first time Harris polls. Also, the polling averages are slowly but finally clearing out all the pre-Biden/Harris switcheroo data, which should mean we're finally getting a clearer picture.
There has been some tightening in the WI/MI/PA firewall towards trump, which is annoying, but not yet worrying. But the bigger changes have been in NV and GA, which have both swung significantly to Harris over the last few days. AZ and NC have both had smaller moves towards dead even, in opposite directions.
Basically the newer polling has reduced some of the safety in the bluer swing states, but has opened up many more paths to victory in the redder swing states. Georgia is the most intriguing one to me because it's big enough to be a realistic alternative to 270 if PA doesn't go blue - because even getting both NV and AZ wouldn't be enough to counteract PA going red.
Note: Nate won't update his with today's new polls until this afternoon, and i'll update this again then. I imagine his new numbers will probably push GA into blue.
And of course, RCP is doing the most shenanigans here, holding onto old trump-favorable data as along as possible. Especially in Pennsylvania as they know how important that state is, and they know as soon as it shows Harris in the lead they have to change all their maps to show Harris winning potus.
