In my experience, the Lefties collect all the ammo they possibly can, prioritize them according to the damage they think each one can do, and lob them out of the depths at the chosen times.
What's entertaining are situations when the main battle is still far from over, but they've run out of all the ammo that made it above the cut-line, ie that barely passed the smell test. At that point they desperately scrape the bottom of the barrel, throwing at their target everything that remains down there, crossing their fingers that something, ANYthing will eventually stick to the target! And not cause an even worse backlash ... they hope.
I remember seeing that pattern at least as far back as the Anita Hill / Clarence Thomas Hearings (intentionally sarcastic use of font sizing). Near the end, Nina Totenberg was running around the halls outside the Senate Judiciary Committee, shocked that the Dems running the hearing were putting an end to it and forwarding the decision to the full Senate for a vote, even though they still had two Stop-The-Presses, Smoking-Gun witnesses who had not yet testified!! Yeah, right. Eventually I found out who those two were: "Smoking gun" my butt; they were the Stinking Trash bottom of the barrel.
Hillary’s people didn’t play the sexist card enough. They went after Trump, but they didn’t play up Hillary. The meme that Hillary cares about children didn’t work well since there was nothing behind it. “Hillary vows to do X to help children” was weak at best. They should have played the grandma angle since age wasn’t a concern.
What I would have done for Hillary is used the millions of miles traveled and shown her with children from around the world. Guess the overlooked that.
The Anita Hill / Clarence Thomas fiasco was a low water mark... The press was at their hateful best - as usual - but our side hadn’t created language to counter them. We’re getting better...
