Wikipedia lists endorsements in each race, e.g. https://en.wikipedia.org/wiki/2020_United_States_House_of_Representatives_elections_in_Texas#District_25. Some tweets by candidates also announce endorsement. Is there some way to find out as many as possible people who run for senator or house representative and have received endorsement from a politician?
I am mainly/only interested in who Bernie Sanders has endorsed, and I am satisfied with those listed in Wikipedia, and only if Wikipedia could be queried ...
Thanks.
