Donald Trump is in the midst of what seems to be a successful campaign to become the presidential nominee for the Republican Party. His golf course, Trump National Doral in Miami, Fla., is hosting the WGC-Cadillac Championship this weekend, but he has yet to make an appearance.

Rumor has it, he'll be at the PGA Tour event Sunday when a winner is crowned champion of the tournament. Trump has, obviously, been very busy, but the guy owns the golf course and was there last year when Dustin Johnson won the event, so it's hard to believe he can't find the time to fly down there in one of his private jets and show his face.

There's been a lot of talk about Trump heading into the tournament and many of the PGA players didn't seem to care for it. When asked about his presidential run, Rory McIlroy, who is from Northern Ireland, told reporters he didn't care because Trump wasn't going to become the leader of his country. Dustin Johnson said he's not really into politics, so such an issue doesn't concern him. And when Bubba Watson was asked about Trump's possible presence at Doral, he said that it'd benefit the players because then they would face less media attention.

There's also been a lot of discussion about the PGA Tour dumping Trump and Doral due to his controversial comments throughout his presidential campaign. Some of his comments have perhaps put organizations such as the PGA Tour in a tough spot in terms of conducting further business because it's a reflection on them.

After Trump said he'd issue a ban on Muslims coming into the United States if he were to become president, the PGA Tour released a statement to ensure they did not support his statements and that it'd "explore all options regarding the event's future."

As you can imagine, Trump isn't very concerned with the speculation after telling Golfweek that he'd perhaps save some money since it's "very expensive" for him to host such an event since he has "100 percent occupancy" of the property. He said it'd be "foolish" for the Tour to move the event elsewhere, but in the end he believes he'd "make more money."

So it might be in Trump's best interests to show up Sunday because it could be the last time Trump National Doral hosts a PGA Tour event.
