All Christie showed in that exchange was how little he knew about Obama and his true agenda. Rubio had said that it was wrong for people to say Obama didn't know what he was doing - that he knew full well what he was doing: intentionally destroying the country. ie, "fundamentally transforming" it. If he did make an error it was in not fighting back harder to make that point clear.
He repeated it four times.
We know The Usurper is intentionally transforming the country. He told us he would.
None of the people we elected to stop him have tried very hard, including Rubio. He tried to give the Democrats a permanent majority with his amnesty plan.
Christie was hugging him.
Cruz voted for cloture on the trade deal.
They have all helped in some way.
Christie simply pointed out what I had seen for myself, Rubio is the Memorizer Bunny.
