Officials in a large North Texas county decided this week to cut more than 100 Election Day polling sites and reduce the number of early voting locations, amid growing concern about GOP efforts to limit voting access ahead of next year’s midterm elections.

The 3-2 vote on Tuesday by commissioners in Tarrant County, which includes Fort Worth, came one day after Donald Trump vowed to end the use of mail-in ballots. The president lacks the unilateral power to decide how individual states run elections, but his declaration speaks to long-brewing and unfounded claims by some conservatives that the country’s electoral system is insecure and vulnerable to widespread fraud.

Trump has repeatedly and falsely asserted that he won the 2020 presidential election instead of Joe Biden.
