民主党有望在11月的中期选举中取得进展，但这主要得益于特朗普总统的不受欢迎，而非该党自身形象的提升。
Democrats are on track to make gains in the November midterm elections, but they are benefiting from President Trump’s unpopularity—not their own party’s image.
事实上，自特朗普去年就职以来，民主党的支持率已降至几十年来最低水平之一。
In fact, Democrats have received some of their lowest approval ratings in decades since Trump took office last year.
民主党选民对于该党应秉持何种立场以及谁最适合击败共和党人存在分歧。
Democratic voters are divided over what they believe their party should stand for and who is best equipped to beat Republicans.
该党的极左翼势力正在崛起，美国民主社会主义者协会及其他进步派成员在一些党内初选中击败了长期在任的议员。
The party’s far-left flank has been ascendant with members of the Democratic Socialists of America and other progressives toppling longtime incumbents in some party primaries.
这是历史上首次有几场竞争激烈的参议院和众议院席位选举由极左翼候选人作为民主党提名人，这也将成为进步派在竞争性选区中实力的一次考验。
For the first time ever, several highly competitive Senate and House seats will have far-left candidates as the Democratic nominees—a test of progressive power in competitive races.
