Keep in mind, Blue MAGA here tried to claim Biden won his debate.
It's obligatory for those on a team to claim they win. If you were voting for Harris before the debate, you are still voting for Harris after the debate. If you were voting for Trump, there is almost no chance that changed based on this debate.
If you are on the right and not voting for Trump this election, you probably aren't voting. Cheney isn't bringing votes to the Democrats.
The votes left to get (amongst registered) are leftists who are still struggling to vote for a candidate who supports a genocide. You won't get them abusing them with the idea that they need to sacrifice their morals for a candidate. Only the candidate can get those voters, and they can only do so with a policy shift. It's probably about 2.5 to 5 percent of registered Democrats s in this bucket. More than enough to make or break the Harris candidacy.

The only other option for more votes is to create more registered voters (link above). So we're very rapidly coming up to the point where neither the Harris or Trump campaign can j crease their vote share in the critical states that are going to decide this election.
Using the relatively well established rule of about 2 weeks for information to filter through the news and to emerge in polling, and the consideration that the voter registration deadline is coming up, that we should expect a policy shift from Harris around October 12th -16th. This is simply because there really aren't any more votes for the campaign to get once the registration deadlines begin to pass.
