Trump called on Republicans to nationalize voting. What does that mean?

President Donald Trump made headlines on Monday when he called on the Republican Party to "nationalize" the voting process without explaining what that means exactly.

"The Republicans should say, 'We want to take over,'" Trump said on former FBI Deputy Director Dan Bongino's new podcast. "We should take over the voting … in at least many, 15 places. The Republicans ought to nationalize the voting. We have states that are so crooked, and they're counting votes."

Trump did not specify which states or jurisdictions he believes Republicans should target, nor did he outline any specific legal or legislative pathway to accomplish such a move. So what is he proposing?

Nationalizing voting means transferring control over elections from state or local governments to the federal government to make the voting process more uniform across the country. Each state decides how its elections are run, ranging from mail-in ballots to voter identification.
