As I understand it, Trump has more or less reached his 'limit' of voters - he's not really adding any new supporters and his numbers haven't changed much since 2016. Harris started from zero (sort of) and although it seems fair to presume that the majority of Dems have switched from Biden to her, she has to convince the undecided independent voters (and reluctant Repugs) get on board as well. She has done remarkably well in a very short period of campaigning but the undecideds will be voters with specific interests and/or grievances that they will want to see adequately addressed.
The election will be decided by those swing states' electoral college votes not the country's popular vote. My DH and DC have postal ballots in Massachusetts - so arguably their vote could be deemed redundant as MA will definitely go to Harris. But they will still send in their ballots - to stand up and be counted!
Some encouraging details here. (Here's hoping all the female voters in the swing states get their act together and vote for Kamala!)

As Steve Kornacki of NBC News explained Monday, the polling gender gap between Vice President Kamala Harris and Donald Trump is "off the charts." New polling by NBC shows a 58-37% split with women favoring the Democrat in the presidential race, but men back the Republican candidate 52-40%. Taken together, that's a shocking 33-point gender gap between men and women.
This is hopeful news for a few reasons. Harris leads with women more than Trump leads with men, pushing her ahead in the national poll. Women tend to vote more than men and, in fact, have turned out in higher numbers in every presidential election since 1980. There's every reason to believe that trend will continue, as concerns about abortion bans continue to activate female voters in large numbers.
