Via TPM:
"It’s fair to assume there may be some leveling off of Kamala Harris’ support. But I don’t think there’s real evidence of some kind of sea change in the race....
The debate is going to be a big deal.
Trump is mostly holding on to his faction of the electorate....a small but significant chunk of voters who are considering Harris but are not yet locked in....the debate itself & the...conversations kicked off by it will play a big part in determining how that all plays out."
