One way is for every decent,hard working American to send $20...$50...$100...or $10,000 to his campaign!
That's my plan.
I have already donated twice before for the '24 cycle what I thought I could at the time. I'm going to donate 4X that much now even though I can't afford to give what I did before.
The timing of it sends a loud message and of course it helps the campaign.
