Donald Trump will find dissy less effective on a national level. The American people aren't interested in a Trump National Enquirer. They want the issues addressed. He should find a transition into an issue related campaign is far better. This 'dissing thing' works for the Republicans, but, not for a larger audience.

It is just the way it is.

Both Senator Sanders and Secretary Clinton have their own ideas about policy issues. The sooner Mr. Trump addresses that the sooner he will find people taking him seriously. 

There are three debates and there won't be any dissy allowed.
