Goldwater makes some statements that make him look extreme and so he loses a great deal of support in the North and elsewhere. His votes for the Civil Rights Acts of 57 and 60 keeps his support modest in the Deep South, but his conservatism does help him in parts of the South and West. Ironically, he takes away support from some who would otherwise vote Unpledged in MS and hands the state to Kennedy, but he does become the first Republican candidate to win SC. Republicans complain of vote fraud in TX.
