JD Vance, others say Biden should resign presidency if he drops out of the race

Senators JD Vance and Marco Rubio, along with pollster Nate Silver and Democratic Rep. Marie Gluesenkamp Perez, are among those suggesting Biden should resign the presidency.

Sen. Marco Rubio, R-Fla., echoed that sentiment to reporters at the Republican National Convention in Milwaukee Thursday. 

"The question is, if he's not going to be their nominee because he's not up to it, how can he be our president for the next six months?" Rubio said, according to Politico. "If there's something wrong with you that doesn't allow you to run for president, how can you still be there as president? If they're going to remove him as nominee, they’ve got to remove him as president, and that's really bad for our country."
