1. According to this poll, she is leading only in one swing state (NV), which also happens to be the smallest of these states. That’s. It a good poll for her.
2. As we discussed two weeks ago, Harris is not particularly popular. She is not a candidate who has a 70-80% of winning. Maybe ~ 50%.
Also, from CNN:
“The Poll of Polls includes
a CBS News/YouGov poll released Sunday that finds no clear leader nationally, with Harris taking 50% and Trump taking 49% among likely voters. That marks an improvement for the Democratic ticket from the final CBS/YouGov poll prior to President Joe Biden’s exit from the race, in which Biden trailed Trump by 5 percentage points. “
So, yes, she’s doing better than Biden, but would it be enough? I don’t know.
