Freed by Court Ruling, Republicans Step Up Effort to Patrol Voting

WASHINGTON — Six months before a presidential election in which turnout could matter more than persuasion, the Republican Party, the Trump campaign and conservative activists are mounting an aggressive national effort to shape who gets to vote in November — and whose ballots are counted.

Its premise is that a Republican victory in November is imperiled by widespread voter fraud, a baseless charge embraced by President Trump but repeatedly debunked by research. Democrats and voting rights advocates say the driving factor is politics, not fraud — especially since Mr. Trump’s narrow win in 2016 underscored the potentially crucial value of depressing turnout by Democrats, particularly minorities.

The Republican program, which has gained steam in recent weeks, envisions recruiting up to 50,000 volunteers in 15 key states to monitor polling places and challenge ballots and voters deemed suspicious. That is part of a $20 million plan that also allots millions to challenge lawsuits by Democrats and voting-rights advocates seeking to loosen state restrictions on balloting. The party and its allies also intend to use advertising, the internet and Mr. Trump’s command of the airwaves to cast Democrats as agents of election theft.
