Would JFK jr. be our president now, if he would have not tried to pilot the plane on that fateful day?

I believe he would have taken that seat in New York away from Hillary, and would have won by a landslide to become as a conservative president as his dad was, even though he would be on the dem's ticket. Who knows? maybe Hillary would be the VP? 0bama would have had more time to gain experience and maybe would have actually done something?
