Trump may get the nomination. There are not enough delegates left for any other candidate to win the required number. If Cruz won every remaining delegate, he would force a contested convention, but still not have the numbers to win.
I have said from the first primary that the only way the Republicans could lose was to nominate Donald Trump. Not so much because there is anything wrong with him, but because of the extraordinary level of antipathy towards him in his own party.
Many of the criticisms of him in the video are unfair. Those who know whim and have worked with him, including women, blacks and Latinos, respect him and felt respected by him. With the right advisors he would make a good president. But will the Republican Party be willing to spend the money and do the work to convince people of that? It will be much harder after videos like this one.
