Historically speaking

I wonder what party he was from ?

Edgefield, South Carolina,
U.S. A staunch opponent of civil rights legislation in the 1950s and 1960s, Thurmond conducted the longest speaking filibuster ever by a lone senator, at 24 hours and 18 minutes in length, in opposition to the Civil Rights Act of 1957.

I must add that in his latter years Strom matured into a Conservative. He was instrumental in Thomas' confirmation.

Yeah, saw that. Ya just never know I guess
Like Wallace was an "Independent" (according to Google) and Alexa. Prick was a stone Dem forever, and think he ran ONCE as a Independent for POTUS ? So he's an Independent. Because the Democrats never had any racists as you know.
