As the presidential race heats up, some democratic candidates have released plans for how they would break up big tech.

The issue didn't come up in debates until October, but since then, other candidates like Andrew Yang have talked about the issue more frequently.

Elizabeth Warren has made breaking up big tech central to her campaign. Bernie Sanders is aligned with her, while other candidates take more moderate positions.

Throughout this campaign cycle, some democratic candidates have turned the conversation to the issue of tech monopolies.

Sen. Elizabeth Warren has been running on a platform of breaking up Facebook, Amazon, and Google, which she compares to big oil, and she recently pledged to stop taking donations from tech executives. Sen. Bernie Sanders has his own plan that would remove concentrated power from tech companies, but he largely agrees with Warren.

Most of the other candidates agree that these companies held too much power and that it is a problem, but they have stopped short of proposing specific plans or calling out individual companies and executives. So far, only Sanders, Warren, and Yang have specific plans detailing how they will handle big tech — the most common position among candidates is support for regulation and antitrust enforcement, but not necessarily using executive power to break up tech companies.

Here's where each candidate stands on breaking up big tech.
