I’m not so sure. Probably a long shot for her to be replaced at this point, but as I stated previously, Dems would change candidates on the ballot the Monday before Election Day if they feasibly could and thought it would give them a better chance to win. They’ll break every rule and norm possible if they deem it necessary to win.They're not removing Kamala. Once the overlord came down from the mountain and endorsed her, there was no going back.
Now, do they have buyer's remorse? Maybe, given the lukewarm movement in the polls, but there is nothing to be done about it now. The ship has sailed.
If Kamala continues to trail in swing states heading in to their convention, or even imagine if she begins dipping after her initial mini-bump, things might get dicey for her.
