Trump has led in both recent polls in early states and nationwide, results that will earn him a spot in next week's first Republican presidential debate in Ohio.
Asked by CNN's Don Lemon aired Tuesday night if he was practicing or otherwise prepping for the upcoming event, Trump said, "I am what I am. I am what I am."
He blasted both former Florida Gov. Jeb Bush and former Secretary of State Hillary Clinton for what he said is an over reliance on the advice of pollsters to gauge the political winds, rather than speak their minds.
