In American Party of Texas v. White, 415 U.S. 767, 94 S.Ct. 1296, 1304, 39 L.Ed.2d 744 (1974), the Supreme Court upheld Texas laws that required petition candidates for state-wide office to obtain signatures from 1% of the voters participating in the last gubernatorial election, even though each signature had to be accompanied by an oath that was notarized, voters who had participated in primary elections were ineligible to sign, and all signatures had to be gathered in a 30-day period.
