Trump's not going to implode as long as the media continues to endlessly blab on about him and cover him at the expense of more promising GOP candidates. The media wants Clinton to win because she's able to pretend to be a progressive liberal democrat while being cozy with Wall St. cronies. The best way to make sure she wins is to associate the GOP with Trump, pushing the GOP further and further to the far-right and by doing so making moderate voters less likely to consider them.
If that's the case (and it very well may be), then I think the media may be out-smarting itself. I don't like Trump, and I can't even really grok the appeal of his campaign. But its quite clear that he's excellent at generating his own buzz, and that he may be able to launch some devastating attacks on Hillary from unexpected quarters. She's a flawed candidate, who only has a shot at the White House because of how awful the Republican bench really is. But I'm starting to doubt that she's up to dealing with Trump, any more than Jeb has been.
