(JTA) — The field of 2020 presidential contenders is a crowded one, to say the least.

We have put together a series of articles that explore the candidates’ (and potential candidates’) Jewish connections — from those who identify as Jews, or are married to one, to candidates who are not Jewish but have ties to the community in different ways. We also explore their views on Israel.

Below are links to articles, sorted by publication date, that our staff has written about some of the political contenders, mostly those seeking the Democratic nomination. This list will be updated as additional candidates join the fray.
