Donald Trump does his best to defeat Trump

Donald Trump, the number one advocate for not choosing Trump, has dragged his feet and when it comes to disavowing David Duke's endorsement of his candidacy.  In most elections, simply receiving such an endorsement would be poison.  If the candidate ran to the microphones and condemned the endorsement within five minutes, it could still spell the end of a political career.  But Trump blathers about, says he might not know who anyone is talking about, drags his feet, says he'll  think it over and?  Yep, he'll still dominate  the GOP polls.  Again, I am not convinced he isn't a plant who is hell-bent on destroying the GOP by trying to show it is everything its opponents have always said it is.
