Quizplus · Accepted Answer

The Democratic Party was the primary supporter of the white primary in Texas. They implemented such measures to exclude African Americans from participating in the primaries and thus, prevented them from having any significant political influence. The party formed a Solid South by controlling local politics, which resulted in the suppression of black votes that continued until the 1960s.
