When Crystal Mason appears in federal court in Fort Worth, Texas, this week she has been warned by her lawyers to be prepared for the worst. Mason, a 43-year-old mother of three, has been sentenced to five years in Texas state penitentiary. All because she committed the crime of voting. On 8 November 2016 ... she walked to her local Fort Worth polling station to perform her civic duty as a US citizen. To her surprise, her name wasn't registered on the voting rolls, so she cast a provisional ballot. She didn't ... know that under Texas's strict electoral laws, she was ineligible to vote. By dint of a previous conviction for tax fraud, for which she had served five years in prison ... she was one of 500,000 Texans barred from the electoral process. After Trump's victory she was called to a Fort Worth courthouse [and] received her five-year sentence for illegal voting. There is a cruel irony to Crystal Mason's predicament. While it is true that Fort Worth has a major problem with democracy ... the crisis is not that people are voting illegally, but that they are not voting at all. In 2016, researchers at Portland State University compared the turnout in mayoral ballots in 50 US cities. Fort Worth ... had a turnout of just 6%. With participation rates at such dire levels, politicians might be expected to try with equal urgency to boost voting. But at both national and Texas state level, the response from Republicans has been quite the opposite - they have embarked on a rash of efforts that tend to suppress turnout.
