Meanwhile, we can expect Donald Trump to attempt to buy delegates just as he has bought politicians his whole career.
I see how it is. If Cruz gets to the delegates (with a bucket load of promises), he is "convincing them to vote their consciences." But if Trump gets to them with his skills of negotiation, he is "bribing" them.
That's just the same kind of weaselly language that we get from lawyers. It is the same activity in both cases, you just describe it differently.
