2020年美國總統選舉民主黨初選

2020年美國總統選舉民主黨初選（英語：2020 Democratic Party presidential primaries）在美國50個州、哥倫比亞特區、五個海外領地及海外民主黨人群體舉行。 各地初選（含黨團會議）將會產生大約3,979名「承諾代表」參與2020年8月民主黨全國代表大會。他們將會選出代表民主黨的2020年美國總統選舉候選人。如果某參選人在初選開始後退選，其在先前各地初選獲得的「承諾代表」可於全國代表大會上改投其他參選人。 民主黨亦會委任771人為「非承諾代表」（超级代表），他們在全國代表大會的投票取向無需依從各地初選結果。與1984年引入超級代表以後的歷屆選舉不同，2020年的超級代表將無權在全國代表大會總統候選人提名的首輪投票投下具有決定性的票。如果需要進行次輪投票，這些超級代表可以投下具決定性的票。 2020年6月5日，拜登正式获得民主党总统候选人提名。 D1 Miami D2 Detroit D3 Houston D4 Westerville D5 Atlanta D6 Los Angeles D7 Des Moines D8 Manchester D9 Las Vegas D10 Charleston 由於參選人數眾多，民主黨早設門檻，即參選人需要收到65,000人次的捐款和民調超過1%（超過20位則由首20位取得資格），才能夠通過參加初選辯論的門檻。布克在5月初才達到門檻，杰伊·英斯利稍後也達到門檻， 但他數月後自己退選了。首次辯論（2019年6月底）有20人參加，但因為民主黨逐步提高門檻，所以半年後，圖爾西·加巴德、朱利安·卡斯特羅、布克等人不再符合資格。合資格出席12月的辯論的人有：拜登、桑德斯、華倫、布塔朱吉、克罗布彻、施泰尔、楊安澤 (4次達到4%的支持度)；加伯德 只有3次達到4%的支持度。分析指，門檻的作用在於儘早篩走支持度低的候選人。 2020年初（第七次辯論），符合資格出席辯論分別為：拜登、桑德斯、華倫、布塔朱吉、克罗布彻、施泰尔。 將於3月15日舉行的第十一次辯論的特別之處，是第十次辯論之後五人退選：施泰尔、布塔朱吉、克罗布彻、華倫、布隆伯格。加巴德雖然繼續參選，但因為支持度不足未能符合出席電視辯論的資格。 在2020年4月8日伯尼·桑德斯宣佈停止競選活動後，乔·拜登已成為僅餘的民主黨主要參選人。 以下在2020年艾奧瓦州民主黨黨團會議舉行後退選，以宣佈退選日期排序（最晚者在前）。 以下在初選前已退選，以宣佈退選日期排序（最晚者在前）。 Due to the COVID-19 pandemic in the United States, a number of presidential primaries were rescheduled. On April 27, New York cancelled its primary altogether on the grounds that there was only one candidate left with an active campaign. Andrew Yang responded with a lawsuit, arguing that the decision infringes on voting rights,[44] and in early May, the judge ruled in favor of Yang.[45] 下面列出各陣營向聯邦選舉委員會申報，在2017年1月1日至2019年12月31日期間籌得和已支出的競選經費。籌款總數是所有個人捐獻、來自參選人的貸款及從其他競選委員會轉撥金額的合計。手頭現金由籌款總數減去已支出金額得出，顯示各陣營截至2019年12月31日可用於未來競選活動的資金。各主要參選人合共籌得989,234,992.08美元。   已退選 數目或會有變。 截至2019年12月估計，數目或會有變。 在艾奧瓦州等4州並非正式候選人。 已退選（下同）。 中途退選。 Amy Klobuchar ends bid to challenge Trump.
