In a 2004 interview, Trump said he identified more with Democrats because he believed that the economy does better under their leadership.

I’ve been around for a long time and it just seems that the economy does better under the Democrats than the Republicans.

Before the COVID-19 pandemic, Trump blamed Obama, Democratic presidential candidates, and the federal reserve for economic problems during his tenure.

I think the financial markets are very upset when they look at the Democrat candidates on that stage making fools out of themselves.

The Fed was not good, as far as I’m concerned, and that was a big blip that should not have taken place, should not have happened…that was just killer when they raised the rate, it was just a big mistake, and they admit to it.
