Kamala is leading in national polls too, but that’s irrelevant to electoral college. Battleground states are always by definition close and unpredictable.

She reversed Trump’s lead over Biden in a couple months so it’s a bit disingenuous to portray her as a notably bad choice. I’d wager very few choices would have amounted to anything other than crowning Trump emperor of the US.

There will be plenty of time for complaining under the hellscape of another Trump administration so take advantage of the slight ray of hope you’ve been given and see where it goes first.
