The fourth fundraising quarter of 2019 ended on December 31, and 2020 Democratic presidential candidates are beginning to report how much they've brought in.

There are currently 14 major Democrats in the 2020 primary field — and they're fiercely competing for donations in order to rise to the front of the pack a little over four weeks before the Iowa caucuses.

Almost all of the Democratic contenders have pledged to run grassroots campaigns, with many rejecting donations from corporate PACs, federal lobbyists, and fossil fuel companies.

The Democratic National Committee raised the fundraising stakes even more by requiring 2020 Democrats to reach 5% in four national polls and secure 225,000 individual donations from donors in at least 20 states to qualify for the next Democratic primary debate in January.

Out of the eight Democrats who have announced their fourth-quarter fundraising totals, Sen. Bernie Sanders leads the pack with $34.5 million followed by former Mayor Pete Buttigieg with $24.7 million.

Notably, Sanders and Warren are the only two candidates who have completely sworn off not just PAC money but all private, high-dollar fundraisers and are completely relying on grassroots donations, speaking to the power of the digitally-driven small-dollar model.

On the GOP side, the Trump campaign and the Republican National Committee announced raising a combined $154 million for President Donald Trump's re-election campaign in the fourth quarter, blowing Democrats' fundraising out of the water.

Here are all the 2020 candidates who have announced their third-quarter fundraising and how much they've raised. This post will be updated as more 2020 candidates report their third-quarter fundraising.
