Because he used to be a democrat, and is now running as a Republican in an already difficult election for Republicans. Now he threatens to go independent.
In most elections where a third party candidate has aligned with the interests of the two major parties of the day, the spoiler effect has occurred.
The first recorded one was James Birney for Henry Clay, allowing James K Polk to be elected.
More famously are William Howard Taft and Theodore Roosevelt in fighting allowing Woodrow Wilson to win.
And in the recent past, Ross Perot for Bush Sr., and Nader for Gore.
These are not very isolated incidences, and the ramifications of the spoiler candidate have quite literally altered the course of history.
So why would Trump go ahead if not to sabotage the Republicans?
Narcissism. Therein lies the answer.
Perot siphoning support from Bush I might not be as true as everybody assumes. The Republicans put the blame on the Perot campaign because it was an easier excuse for their loss, but Perot's base was not "stolen" exclusively from the right wing.
In 1992, Perot got 19% of the vote, but in 1996 he only managed 8%. Where did half of his support go? Not back to the Republican party: Dole only managed about 2% more than Bush did four years earlier.
