Trump Threatens a Presidential Bid : Afternoon

A new book is set to hit store shelves from Donald Trump.  In it, he says that he just might make a run for the White House if the Republican Party doesn't put up a sufficiently good enough candidate.

An aide to "The Donald" says that he would likely not run against Newt Gingrich, since he and Newt are close, but wouldn't say what other candidates would be strong enough in his mind.

Is this good or bad as we look at the next election?
