New Pro-Trump Super PAC Quietly Spends Millions on G.O.P. Ground Game

Republicans have quietly formed a new super PAC that is preparing what appears to be a significant push to persuade former President Donald J. Trump’s voters to vote early or by absentee ballot.

The group, America PAC, was created last month and remains fairly secretive. But over the last two weeks, it has spent $6.6 million on behalf of Mr. Trump, the presumptive Republican nominee, according to public filings, vaulting it suddenly into the top tier of pro-Trump outside groups in the general election.

On its little-publicized website, the group is collecting voters’ information and encouraging them to register to vote, to request an absentee or mail ballot, or to pledge to vote, calling the race “the most consequential election of our lifetime.”

People who enter their ZIP code are directed to the form on an official state election website where they can complete their voter-registration forms. Voters who put in their information for an absentee ballot are assured that they will be sent more information shortly. And those who pledge to vote are informed that the super PAC will “stay in touch” with them.

“Register to vote,” reads the website. “Make a plan to vote early in person or by mail. Vote and have your say if America can be a land of freedom and opportunity for all. We can have the greatest election victory in America’s history when you vote!”

The marketing materials may be primitive, but the size of the expenditures suggests that the group probably has eight figures’ worth of funding. Over the last few months, since Mr. Trump secured the Republican nomination, several new super PACs have sprouted up to try to support his operation.
