The best campaign was Trump's on social media. He also spoke to people like Joe Rogan and Elon Musk. Surprisingly, his speeches were far more coherent than those of Harris.
Like Harris, he used identity politics, but he also had someone very bright on his staff. Who would have thought of getting 178,000 Amish to vote in Pensylvannia? They don't vote. He found a grievance, and his people signed up the lot of them. He want after the Jews. 78% voted for Trump - switching from Democratic.
I don't know who managed his campaign, but the results speak for theemselves.
