This is a lie. In his concession speech(oddly enough that part was left out of this article)JD said that the time for derision was over and it was time to support the Republican candidate. He said this after the crowd started jeering McCain. Why this writer tries to make JD sound like an a**hat is not to much of a mystery, my opinion that the article is written to make JD look like just as big a jerk as McCain when it comes to his Republican opponents.
And....the poster added the headline that “JD wouldn’t support McCain”, which you have shown to be untrue.
