There is no "bigger picture". Trump made Carson a deal. That is all this is.
*sigh* what do you base this claim on? It's just yet another of a long list of baseless claims in a political season. You are, basically, calling Carson a liar as to his inner motives for backing Trump.
Carson has
never given the American people
any reason to believe that he is concerned with anything other than its well-being. He has taken the hippocratic oath to "
first, do no harm." And he has kept that oath his entire life as a Doctor. Why would he break from that oath now when it matters most?
And I would say the same thing about Bernie Sanders. . . even though I fundamentally disagree with his political views, I'm not about to demonize him by questioning Mr. Sanders' motives. That, simply, would not be right. And it would stifle sincere discussion if I did that.
There
is a bigger picture. . . the Supreme Court. If we don't see that. . . we risk losing it.
Kasich and Rubio need to drop out. This should be a two man race between Trump and Cruz. The Supreme Court is at stake here. And Carson clearly understands this.
That's his true motive for backing Trump.
