Republicans are launching a voting bill debate that could last days or even weeks

Instead, Republicans intend to make a long, noisy show of support for the legislation, which would require Americans to prove they are U.S. citizens before they register to vote and to show identification at the polls, among other things. It's a risky strategy, with no guarantee it will be enough for Trump, who has said he won’t sign other bills until the Safeguard American Voter Eligibility Act — also known as the SAVE America Act or the SAVE Act — is passed.

The floor debate is expected to eventually end with a failed vote. Republicans need 60 votes to advance the bill to a final vote, but they hold 53 seats, and all 45 Democrats and both independents, who caucus with the Democrats, oppose it.

Still, the debate will “put Democrats on the record,” Thune said last week.

In a social media post on Tuesday morning, Trump issued a warning to any Republican who doesn’t vote for the bill: “I WILL NEVER (EVER!) ENDORSE ANYONE WHO VOTES AGAINST ‘SAVE AMERICA!!!’”

Creating strict voter registration rules

Trump says, without evidence, that Democrats can only win in the midterms if they cheat and explicitly said Republicans need the SAVE America Act to win in November. The House passed the legislation earlier this year, but the Senate turned to other issues as it became clear that Republicans didn’t have the votes to pass it.

But Trump made clear he wasn't satisfied and pushed the Senate to act. The Republican president has said he won't sign other legislation, including a bipartisan housing bill backed by the White House, until the voting bill passes.

The bill contains a slew of provisions that Trump and his most loyal supporters have pushed as part of a broad effort to assert federal control over elections. It would require voters nationwide to provide proof of citizenship when they register and to show accepted voter identification when casting a ballot.

It would also create new penalties for election workers who register voters without proof of citizenship and require states to hand voter data over to the Department of Homeland Security so federal officials could screen for voters who are in the country illegally.

Trump also wants new provisions added to the bill, including a ban on most mail-in ballots.

“It’ll guarantee the midterms,” Trump said of the bill last week. “If you don’t get it, big trouble.”

Democratic opposition to the bill is firm

Democrats and many groups that champion voter access say there is little evidence of noncitizens voting and say the bill would disenfranchise millions of voters — including Republicans — by creating new burdens to prove citizenship.

It is already illegal to vote if you are not a U.S. citizen, but the bill would lay out strict new rules for paperwork that people would have to present to register to vote. Opponents of the measure say those documents are not always readily available for many people.

“There is no new problem to solve here,” said Janai Nelson, president and director-counsel of the Legal Defense Fund, a civil rights law advocacy group. “There is an apparatus already to ensure that elections are safe and secure and that only eligible voters are casting ballots in our elections.”

Senate Democratic leader Chuck Schumer said that Democrats are not opposed to voter identification but “this is about purging the voter rolls in a massive way, so you never even get the chance to show a voter ID when you showed up to vote because you’d be knocked off the rolls.”

Expect a show on the Senate floor

Trump, backed by Republican Sen. Mike Lee of Utah, has pushed for a talking filibuster, which would force Democrats to talk for days or weeks to delay passage of the bill. But Thune and the larger GOP conference rejected that idea, arguing that it would end in failure after giving Democrats a stage and the opportunity to offer endless amendments, potentially adding their priorities to the bill.

Republicans are instead taking over the floor with their own speeches, proceeding under regular order but operating outside the normal time limits that are customary when debating legislation. Democrats are expected to answer with their own procedural hijinks, potentially forcing Republicans to come to the floor at all hours for votes, meaning they will need to stay close to the Senate for the duration.

Lee said last week that it’s unclear how it will all play out. He said he thinks Trump “understands that we need to put in an aggressive effort here.”

“And a lot of that,” he said, "is going to have to be determined in real time as we go about it.”

The extent of Trump’s satisfaction with the process, Lee said, “will depend on whether, in his view, we gave it everything we have.”

On Monday night, Lee was rallying Trump’s base voters on X.

“Once we’re on this bill," he wrote, “we must stay on it until it’s passed into law.”
