You don't need to "dazzle" to win elections, you just need to be very clear about what you'll actually do if elected. Existing isn't enough to win votes.

I did quite a bit of research before the election, and I still can't tell you anything concrete that Harris plans to do, not even in the first 100 days of being elected. Here's the best I got:

• ban "price gouging" - what does this mean? Price caps? I don't think she's that crazy, this feels empty
• taxes - these are somewhat concrete, but new revenue will likely be low because wealthy people are good at avoiding taxes
• immigration - one of her major jobs as VP was border security, yet she didn't do much, so I question how committed she actually is to her proposed changes, nor do I know if she wants to increase or decrease net immigration

So, her plans are either vague or seem ineffective, so what would she actually do in office? It's not clear, and it seems like she's running just because the DNC needs someone to run. I don't want a President who is running just because their party said so, I want a President who sees actual problems and has a plan to resolve them.

That said, my vote absolutely doesn't matter because my state has consistently gone to Republicans, and will consistently go to Republicans for the foreseeable future, so I don't know what people in swing states think. But what I do know is that her campaign was entirely uninteresting.
