Legislation that would require proof of citizenship to register to vote was only the beginning as the G.O.P. presses to sharply limit voting in line with President Trump’s false claims of widespread fraud.
The strict voter identification measure that Republicans have pushed through the House is just their opening salvo in a broader legislative effort aimed at keeping control of Congress this fall and helping to amplify the president’s false claims of mass voter fraud in the event that they lose.
The G.O.P.’s relentless focus on the bill and an even more restrictive measure making its way through the House — both of which face a steep uphill path to becoming law — is aimed chiefly at intensifying pressure within their own ranks to muscle through new voting restrictions and seek to reshape the electorate in their favor.
