When did Trump ever campaign on raising taxes?

Perhaps you mean the tariffs which he promised that other countries will pay for?

It was a lie, but it was still a campaign to raise taxes on Americans.

To call it a "campaign to raise taxes" I think assumes voters are more informed and open minded they they really are.

My boomer parents genuinely believed Trump had and would continue to reduce their taxes. When confronted with tariff facts they counter with more spin, like "he's just negotiating" or "it'll make the economy so much stronger".

He's making the trains run on time.

Before I learned it was an infamous political meme immortalized by the fallout from WWII, I heard that claim recited in utter sincerity in the 1990s by a woman who had been a teenager in Italy during that period. Even after what happened with Mussolini, she still believed.
