Supporters say the added enforcement will root out instances of fraud and assure the public that everything possible is being done to make sure that American elections are accurate and legitimate. Critics say the efforts can easily be abused and used as political cudgels or efforts to intimidate people from registering and voting. And Democrats say the main reason Republican voters have lost faith in the electoral system is because of the incessant Republican focus on almost entirely imagined fraud.

The most concrete proposal is in Florida, where Gov. Ron DeSantis asked the State Legislature last week for $5.7 million to create a 52-person “election crimes and security” force in the secretary of state’s office. The plan, which Mr. DeSantis has been touting since the fall, would include 20 sworn police officers and field offices statewide…

None of the three states — and for that matter, none of the other 47 and the District of Columbia — reported any more than a minuscule number of election fraud cases after the 2020 races. Mr. DeSantis said after the 2020 vote that his was “the state that did it right and that other states should emulate.” The only notable hint of irregularity in Florida was the recent arrest on fraud charges of four men in a retirement complex north of Orlando. At least two of them appeared to be winter Floridians accused of casting ballots both there and in more frigid states to the north.
