Every time I look at the polls and bookmakers odds Kamala Harris odds very, very slightly improve. We've now reached the point where she is favourite to win the popular vote and 50/50 vs Trump to be President, which is better odds than the Democrats have had for ages.
This would seem to me to mean that spending your time working for the Kamala Harris campaign, or donating, might be a good use of your time or money since it could be a very close election again. (As a foreign national living in another country, I likely won't be allowed to donate.)
Another Trump Presidency could be even worse this time since all the key appointees will be dumb/bad/MAGA etc. A lot of the sensible adults in the room resigned or were fired in the last Trump Presidency or wrote critical books etc... they won't be coming back.
