Eh, I'll concede that she wasn't screaming her ideals as loud as possible, but that goes back to my original point. The political left is a fickle voter base. Kamala had good ideas, she had policies, she had been part of the successes made under Biden, but she put most of her focus into attacking Trump. It sounds like the argument being made is that uninformed voters weren't encouraged enough to vote and more liberal disenfranchised voters didn't turn out because they didn't like her policies. If this is the case which makes more sense:

1.) Making some policy changes so they can get people who don't historically come out to vote to do so or,

2.) Making some policy changes so that people who historically come out to vote will vote for them.

Someone threatening not to vote, when they historically don't anyways, isn't much of a threat or motivation.
