YES!!!
(also notice Trump's wording. He isn't saying no to a third-party run)
Have we ever had a third party President? If not, I think Trump could be the first. For every uber liberal socialist Democrat there are two who hate illegal immigration and are tired of jobs being outsourced. I can see Trump having broad appeal across Party lines.
One more thing. If the GOPe forces another moderate skunk into the nomination, there will be a huge outcry for Trump to run third party and I think he will.
...... Trump is like the Abrams tank on the battlefield .... after blasting and plowing through heavily fortified walls .... the rest of the troops are free to enter and take care of business quickly while the OPFOR is caught with their collective pants down.
...... He is doing the Republicans a great service by doing this .... and they better get their asses in gear and use the teaching opportunities afforded to them by Trump .... Take advantage of the NOW ... don't wait until the situation cools and the MSM regains their propaganda prowess. Otherwise .... messages will be buried and spun by the masters of deception and the fathers of lies. They will return to being gagged and the messages will never be heard. And it will all be their fault.
