01 · The bio

Who they are.

Founder of Bloomberg L.P., three-term New York City mayor (2002-2013), 2020 Democratic presidential candidate. Bloomberg's political-spend profile is unique: he ran for the Democratic presidential nomination spending roughly $1 billion of his own money in 2020 before withdrawing, then redirected major giving toward climate, gun-control, and anti-Trump infrastructure across 2020 and 2024.

Questions about Michael Bloomberg.

How much did Bloomberg spend on his 2020 presidential run?

Bloomberg self-funded his 2020 Democratic primary campaign with roughly $1 billion of his personal wealth before withdrawing in early March 2020 after a poor Super Tuesday showing. That figure makes it the most expensive self-funded presidential campaign in US history by a wide margin.

Is Bloomberg a Democrat or Republican?

Bloomberg's party registration has shifted: he ran for NYC mayor as a Republican in 2001, was independent in 2008-2018, registered Democratic for his 2020 presidential run. His political giving since 2018 has been heavily Democratic, focused on climate, gun control, and anti-Trump infrastructure. He is best understood as a cross-partisan technocrat who currently aligns with the Democratic Party.

What is Everytown for Gun Safety?

Everytown is the largest US gun-control advocacy organization, founded and primarily funded by Bloomberg in 2014 as a merger of Mayors Against Illegal Guns and Moms Demand Action. It has been the dominant counterweight to the NRA in state-level gun-policy fights since the late 2010s and is the primary vehicle for Bloomberg's gun-control political-giving footprint.
