While he was governor, Byrd built up contacts with the "courthouse cliques" in most of Virginia's counties. He curried support from the five constitutional officers in those counties (sheriff, Commonwealth's attorney, clerk of the court, county treasurer, and commissioner of revenue). This formed the basis of the Byrd Organization, which dominated Virginia politics well into the 1960s. They carefully vetted candidates for statewide office, and Byrd only made an endorsement, or "nod," after consulting with them. Without his "nod," no one could win statewide office in Virginia. While he was governor, he shortened the ballot so that only three officials ran statewide: the governor, lieutenant governor and attorney general. This limited opportunities to challenge the candidates that he wanted to run. His secondary roads bill in 1932, which became known as the Byrd Road Act, did not apply to the state's independent cities.
