Voters head to the polls today for a midterm election that’s widely seen as a referendum on Donald Trump’s presidency, with both houses of Congress and 36 governor’s races in the balance. Thirty-six million Americans voted early this year, with participation high among young people and people of color. That’s up from 27 million four years ago, leading many to predict a record turnout for a midterm election. Politico is reporting that glitchy voting machines in Texas and Georgia have caused some votes for Democrats to be switched for the Republican candidate or deleted. Experts have said the error is a technical malfunction. Voters and civil rights groups in Texas and Georgia have filed complaints in what are two of the most closely watched states this midterm election.
