National Enquirer, WWE, Donald Trump all appeal to a certain class of people that believe they are all real.
The National Enquirer peddles the type of tabloid trash Trump revels in. Trump has turned the GOP primary into a circus of insults, bullying, belittling, endless lies, etc.
I’m guessing if this story dies off quickly and/or gets almost no play, Trump will find a way to retweet it to generate some interest in it.
Might be a bit tough since one of the women already categorically denied it and one of the others appears to be his press spokesperson (who will almost certainly also deny it).
