RCP's still rigged average has Biden's lead up to 9.2, but it's 10 among those polls taken at all after the debate.
It was 6.1 a week ago today.
And 5.8 on September 17th.
Last time it was above this, at 9.3, was the end of July. (It would be 9.3 today without their ignoring the more recent Ipsos poll for some reason.)
270toWin has Biden's lead up to 10.8.
