Until the end of business today, Texans will have to register to vote in the upcoming primary runoff election or update their addresses. The state postponed the election initially scheduled in May until July 14 because of the Coronavirus pandemic. Voters who cast ballots in the March Democrat and Republican primaries cannot vote in a primary runoff different from the one they participated in then. Those who didn’t vote in the March primary are free to vote in either party’s primary-runoff.
