The longest filibuster by a lone Senator went to Strum Thurmond, but evidently a team of Senators were able to filibuster for 57 days.

“Thurmond was not the only lawmaker to filibuster on the issue, however. According to Senate records, teams of senators consumed 57 days filibustering between March 26 and June 19, the day the Civil Rights Act of 1957 passed.”
I’m guessing that the TEAm of Senators that filibustered the Civil Rights Act were ALL DEMOCRATS!!!! Am I right??
