Democracy ended when the DNC undermined the Sanders election campaign so that Joe Biden could get the nomination and become president, but that was only the most recent example.

Before that democracy died when George W Bush and his family stole the election from Al Gore.

Before that it was Nixon and watergate.

Before that it was JFK.

Internationally the US empire has undermined democracies around the world by setting up puppet regimes across Latin America and the Caribbean, Asia and the Pacific, and Africa.
