Trump, who leads in the South Carolina polls by almost 19 points in the RealClearPolitics average of polls, admitted that if he were currently in his last year as president he would likely try to appoint a Supreme Court nominee, and predicted that Obama will nominate someone despite Republican pushback.
Senate Majority Leader Mitch McConnell (R-Ky.) and top Senate Republicans have said they believe the next president, not Obama, should appoint Scalia's successor to the Supreme Court, leaving a vacancy on the high court for approximately a year.
Democrats argue that move would be irresponsible, and Obama pledged Saturday evening to nominate someone to fill the seat. 
Scalia, 79, was found dead during a hunting vacation in Texas.
