Sen. Kamala Harris is leading the pack of 2020 Democratic presidential candidates when it comes to outlining executive action she would take if she were elected and her proposals were thwarted by Congress.

For all the focus that there has been on big ticket items Democrats are proposing, the reality is that even in the best case scenario, the next Democratic president will be taking office with a razor-thin Senate majority, and passing anything major would require nuking the filibuster and winning the votes of Democrats representing traditionally red states.
