Tariffs, tax cuts, no tax on tips, and demanding the FED lower rates regardless of economic conditions, won't help your proclaimed grievances. Biden made a mistake 3 years ago. He's not done it since. Your guy is suggesting bigger mistakes...after the fact.
And he lied. Tried to steal an election. And has been deemed unfit by those who know him best.
