The ongoing legal wrangling over voting rights and access, an issue that has become an undercurrent of the 2020 election, foreshadows some of the expected clashes to come ahead of November’s uncertain general election. The quarrels center on expanding mail voting as states adjust to the unprecedented coronavirus crisis, particularly in key battlegrounds that could tip the scales of the upcoming presidential contest. In states such as Georgia, Texas, Nevada and Florida, among others, state and party leaders are seeking to change the way people vote to avoid a similar fate as Wisconsin, where a series of emergency orders and legal challenges earlier this month culminated in thousands of voters risking their health to stand in long lines for hours to vote. Since Wisconsin's election, state health officials said Tuesday that 19 people who have either voted in-person or worked at a polling site on election day have so far tested positive for COVID-19 after April 9, two days after the spring election — underscoring the potential risks of forging ahead with an in-person voting during the height of the widespread and deadly public health crisis.
