This article comes from one of the very well respected fact-checking groups, Politifact. When Governor Abbott's long standing support for the prevalence of voter fraud was directly challenged by President Obama during a visit to Austin, the governor responded strongly. When Governor Abbott used the adjective "rampant," this triggered many different media outlets to search for supporting evidence. When Politifact went knocking on doors in the state government for supporting facts behind the governor's statement, the governor chose not to reply, but the state attorney general's office provided some numbers on voter fraud cases. Politifact also found some data in a Heritage Foundation report, one that should be favorable to the governor's position since it is a very conservative policy think tank. What was the approximate total number of recent cases between these two sources?
