Presidential candidate Donald Trump, early in his campaign, refused to rule out running as an Independent, saying he didn’t want to give up the leverage.

Then he very publicly signed a pledge not to run as a third party candidate and to support the Republican nominee.

Now he’s renewing his threat.

Republican presidential front-runner Donald Trump suggested Sunday that he would be open to running for president as an independent if he concludes Republicans aren’t treating him “fairly.”

With this demonstration of the value of his word, in what way is Trump distinguishable from the Democrats against whom he purports to be running—as a Republican or as an Independent?
