Donald Trump at the Family Leadership Summit: "No"....I Will Not Go On Record And Say I Won't Run As a 3rd Party Candidate

Hello President Hillary Rodham Clinton....

First question during the Q&A is about running 3rd party. Guy asks Trump, as you know, Ross Perot cost us the election in 1992, will you go on record today and say you won't run as a third-party candidate if you don't get the nomination?

You'd think Trump would say yes and commit to absolutely supporting the Republican nominee so as to defeat Hillary in 2016. But Trump says no.
Ugh.
