So can’t use that against him now.
Via Daily Mail:
Donald Trump ruled out a third-party run for president on Thursday, announcing in the lobby of his landmark Trump Tower in New York that ‘I will be totally pledging my allegiance to the Republican Party and to the conservative principles for which it stands.’
‘I have signed the pledge,’ he told journalists and supporters.
Trump’s press conference followed an afternoon meeting with Reince Priebus, the chairman of the Republican National Committee.
His campaign announced the event after the RNC began circulating a pledge to its 2016 presidential candidates that would commit them to supporting the party’s eventual 2016 nominee.
It also requires them to forgo a third-party bid if they should come up short in the party primary races.
