President Donald Trump and Senate Majority Leader Mitch McConnell have tried to make it clear: Given the chance, they would push through a Supreme Court nominee should a vacancy occur before Election Day.

The issue has taken on new immediacy with the disclosure Friday that Justice Ruth Bader Ginsburg is receiving chemotherapy for a recurrence of cancer after four earlier bouts with the disease. The 87-year-old liberal, who apologized in 2016 for her pointed public criticism of Trump during his first campaign, says she has no plans to retire.

The development has focused even more on what's at stake this election, with the winner in position to help shape the trajectory of the court for years to come.

Trump administration officials have underscored that Trump would not hesitate to fill an opening before voters have their say Nov. 3, less than four months away, on whether to give him a second term.

Four years ago, also in a presidential election year, the GOP-controlled Senate refused to vote when President Barack Obama, a Democrat, nominated Merrick Garland, a federal judge, to succeed Justice Antonin Scalia after his death in February. Nine months before that year's election, McConnell said voters should determine who would nominate the person to fill that seat.
